Re: [algogeeks] apti
if the cyclist would have left on time, then in those 20 minutes, he would have covered 4miles at a speed of 12miles/h so he would have been 1 mile before station whereas train would have been 5 miles before as it is on its normal time, so no change in its position. then, when the cyclist covers that 1 mile, the train covers 5 miles so that both of them meet at the station. thus, speed of the train = 5*speed of cyclist = 60 miles/hour On Sun, Aug 21, 2011 at 12:19 PM, prasanth n nprasnt...@gmail.com wrote: @gupta: can you explain your answer?

Re: [algogeeks] difference between the two
that means the order is immaterial. the sizeof the struct always remains same irrespective of the order and just depends on the type of variables??? why char with double does not get size in multiples of 8?? On Sat, Aug 6, 2011 at 12:54 PM, Puneet Gautam puneet.nsi...@gmail.comwrote: Sorry guys, int is 4 bytes on 64 bit and 2 bytes on 32 bit system.. But padding rule remains same for both structures as mentioned above... On 8/6/11, Puneet Gautam puneet.nsi...@gmail.com wrote: There is no difference between the two... On 32 bit system, both structures need every address location where int and pointer are stored to be a multiple of 4(highest size is 4).. On 64 bit, even if pointer is 4bytes(say, in 64 bit system), and p1, p2 be structure variables, then p2 should start at address which is multiple of 8 as int data is 8bytes. So, if p1 starts at 0, it should end at 16 not 12 so that p2 starts at 8's multiple. This is done by padding pointer by 4bytes in both I and II struct. declarations. Hope i made it clear...! Thanks.

Re: [algogeeks] Re: Novell - Puzzle
@Nikhil Once the rabbits are mature, they should be able to produce babies every month. after 2 months a female produces new babies for first time. but then they should be able to produce a new pair at the end of the third month as they can again mate at the end of second month. Like in the cow problem also, it gave birth to a young one for the first time at the age of 2 and then every year. Hope this logic is right.

Re: [algogeeks] Re: rotate a matrix NVIDIA question
If this is the case, we can follow this method:
take variables
1. dir = 1
2. st_col=0
3. end_col = n-1
4. st_row = 1
5. end_row = n-1
6. row = 0
7. col = n-1
8. noOfCellsVisited = 0
dir are as follows:
1 - left ro right
2 - top to bottom
3 - right to left
4 - bottom to top
row will keep account of the row we will traverse when dir=1 or 3
col will keep account of the column we will traverse when dir=2 or 4
st_col and end_col will keep account of leftmost and rightmost columns for
traversing rows
st_row and end_row will keep account of topmost and bottom rows for
traversing columns
while(noOfCellsVisitedmn)

Re: [algogeeks] Re: Puzzle
Sory once again for that incomplete answer.
The complete one is here.
probability that i win standing at second position: 1/365
probability that i win standing at third position : 364/365*2/365 =
1/365)*(628/365)
probability that i win standing at fourth position : 364/365*363/365*3/365
probability that i win standing at 4th position :
364/365*363/365*362/365*4/365
probability that i win standing at (n+1)th position:
(365-1)*(365-2)*(365-3)*(365-
4)*(365-5).*(365-(n-2))*(365-(n-1))*(n)*(1/365)^n
there is a pattern in the probabilities
let probability of winning standing at nth position be x
probability of winning standing at (n+1)th position = x * {(365 - n +1)*(n)}
/ {365*(n-1)}
maximum probability is at nth position if at (n+1)th position,
{(365 - n +1)*(n)} / {365*(n-1)} = 1
This is true for n=20
For n=19,
{(365 - n +1)*(n)} / {365*(n-1)}1
So max probability is when *n=19*
i.e., n+1 = 20, which is my position.
So standing at 20th position gives me maximum chance of winning
Just hope I haven't got anything wrong here.

Re: [algogeeks] Re: help to code
Evenly divisible simply means that a number should be completely divisible by the given numbers, i.e., it should give a whole number as an answer when divided by that particular number. Evenly divisible doesn't mean that quotient should be an even number. It just needs to be a whole number.

Re: [algogeeks] Re: Some adobe interview questions.
You have given solution for number of coins required for different sum as
explained on topcoder tutorial.
But I think the question has put forward some conditions based on which it
asks us to find the denominations of the 6 coins.
You have taken the sum given(which cannot be obtained by using coins we
have) in the problem as denominations.
I think you have interpreted it erongly.
Just hope my interpretation is correct :)
On Tue, Jul 5, 2011 at 5:25 PM, Azhar Hussain azhar...@gmail.com wrote:
What I understood from the statement is what is the 'minimum denomination'
required for a given value.
I will try to explain it in short
we can solve the problem as sub-problems
Lets say you want a denomination for some sum S and 'i' be the previous sum
so i = S.
If we can find the sum at i we can find the sum for i+1 using i as our
reference.
For example S= 15. What is the minimum denomination required using the
coins 5, 10
from the statement above I cannot calculate sums other than multiples of 5.
So, I will write down sums which are multiples of 5 upto 15.
0
5
10
15
Inorder to calculate denominations for 15. I must have calculate
denominations of 15, 5, 0
Goal:
First 0, this does not require coins so coins are 0.
Sum 5, we have found the solution yet for this mark it as infinity. We see
that there is only one coin in the denomination pool which is less than this
sum.
Sum 10, If I can take the previous sum 10 - 5, I will end up having 2 coins
but the best solution would be denomination of 10 i.e., 1 coin. I compare
the denominations value and the previous sum and store the minimum value.
Sum 15, From the previous step 1 coin for 10 and 5 denomination will make
up the sum so number of coins are 2.
this can be recursively defined as
if ((N[j] = i) ((Min[i-N[j]] + 1) Min[i]))
Min[i] = Min[i-N[j]] + 1;
Where N is the denominations
i is the Previous Sum denoted as Min
j is the index of denomination
sum[1,, 15] = infinity;
for sum 0 i = 0; N[0] = 5 and 5 = is false sum remains 0, so Sum[0] = 0.
for Sum 5 i = 5 ; N[0] = 5 and 5 = 5 true and (Sum[5-5] + 1) Sum[5]
update the sum[5] = sum[5-5] + 1;
+ 1 because including N[j] coin makes the sum
do the same for remaining sums.
can be represented mathematically like this
*C*(*N*,*m*) = *C*(*N*,*m* - 1) + *C*(*N* - *S**m*,*m*)
Or This is the least I can say.
M(j) = Minimum number of coins required to make change for amount of money
j.
M(j) = Min { M( j - vi ) } + 1;
i
complexity O(n^S) for the Sum S.

Re: [algogeeks] Puzzle
Let speed of boat be x miles/hr Let speed of river be s miles/hr First Method: Hat comes down 1 mile in 10 minutes. Hat comes with flow of river only. So its speed is equal to speed of river. In 60 minutes, it will travel 6 miles. thus, s = 6 miles/hr Second Method: Distance travelled upward by boat = 1 + (5/60)*(x-s) miles Distance travelled downward by boat = (5/60)*(x+s) miles Both are same, so 1 + (5/60)*(x-s) = (5/60)*(x+s) x gets cancelled, and we have s/6 = 1 s = 6 miles/hr Second method is just one possible method which nobody would like to follow.

Re: [algogeeks] Reversing the order of words in String
I read that solution.
But the same doubt as Navneet which I think you also raised i one of your
posts on that thread

Saurabh,
I understood your solution but wonder if it is purely single traversal
In affect, you have a second traversal when you are popping the
strings from stack to form the reverse order string.
Though the second activity is less than O(n) i.e. O(#words in string)
Nice solution, this way we can also get rid of extra spaces easily in
the actual string if that is also to be done.

Re: [algogeeks] help to code
I think you are getting it wrong. Surender, your solution says that numbers divisible by all of the first 5 prime numbers will be taken into account whereas the question says that only the numbers *not* evenly divisible by *any* of the first 5 prime numbers are to be added. Shiv, you are making two mistakes: 1. you say n is also included but your code excludes it. 2. you are just checking if a number is not divisible by one of the 5 prime numbers. If it is not divisible by any one number, you add it to your result, whereas your language of the question suggests that it should be that numbers which are not divisible by any of the five numbers, i.e., not divisible by all the 5 numbers ( not the ones divisible by just ant one of the 5). Hope I am correct in my interpretation. -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Re: [algogeeks] help to code
If my interpretation is right, following should be the code.
int main()
{
int userInteger = 0;
cout Enter A Number endl;
cin userInteger; // Ask For a number from the user
if (userInteger 0) // Is the number valid?
{
int result = 0;
int prime[5] = { 2, 3, 5, 7, 11 };
int a,b, count = 0;
*for(a=1;a=userInteger;++a) // Looping to user's input
{
for(b=0;b 5;++b) // Looping the prime numbers array
{
if (a % prime[b] == 0) //if divisible by any number, just end it there
break;
}
//break or end of loop will bring the control here
if(b==5) //a was not divisible by any of the first 5 prime numbers
{
result+=a;
++count;
}
}*
cout Numbers Not evenly divisible by 5 prime numbers: count
endl;
cout The Sum of numbers not evenly divisible by 5 prime numbers:
result endl;
}
getch();
return 0;
}
As per my solution,
Test Cases:
1)
userInteger = 20
count = 4
Numbers will be: 1, 13, 17, 19
result = 50
2)
userInteger = 35
count = 7
Numbers will be: 1, 13, 17, 19, 23, 29, 31
result = 133
Even numbers can never be there in this list as they are all divisible by 2.
Bfore 169, only prime numbers can be included.
Hope my interpretation of your question was correct

Re: [algogeeks] Re: Google puzzles
Arpit The formula that you have written is wrong. You would have approached it correctly but the formula written here is incorrect. m= n + (n**1/6* + (n-1)) + ((n**7/6* + (n-1))**1/6* + n-2) +.. If you add all the terms there should be 1/6 in these terms as the terms give the number of medals given on each day. If you use 7/6, you only need to solve for one term where n-6 would come. As the terms in the series when 7/6 is used give the number of medals remaining at (n-i)th day. Sukhmeet, You have to apply the formula n = k - [(n-1) + (1/7)(k- (n-1))] where k is taken to be the number of medals at the start of (n-1)th day. on (n-1)th day, n-1 medals are given. Then (k - (n-1)) medals are left. 1/7 of these are given away as well. So after (n-1) days the medals left are given by RHS of the equation which is equal to n - the medals left which are given on nth day. Solving this equation we get: k - (n-1) = 7/6*n Thus, medals given away on (n-1)th day = (n-1) + (1/7)*(7/6*n) = (n-1) + 1/6*n Similarly medals given away on (n-2)th day = (n-2) + (1/7)*(7/6*(sum of medals given on (n-1)th and nth days)) = (n-2) + (1/7)*(7/6*(n-1 + 7/6*n)) = (n-2) + (1/6)*(n-1 + 1/6*n)) For (n-i)th day, medals given away = (n-i) + (1/6)*(sum of medals given away from (n- (i-1))th to nth day) It goes on like this till we get the term for first day. SO total medals, m = n + [(n-1) + 1/6*n] + [(n-2) + (1/6)*(n-1 + 7/6*n))] +... Put 6 in this equation and we get the required answer m = 36 Simple formula m = n + [(n-1) + 1/6*first term]+ [(n-2) + (1/6)*(sum of 1st and 2nd term)]+ + [(n-i) + (1/6)*(sum of all terms till now)] + i goes upto n -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

bittu, you have written this code at end of main() *printGivenOrder(start); printList(rslt);* so the BT in spiral order should be printed twice But you are getting a extra 4 only in place of the whole tree because of these lines *temp=current; current=head; rslt=appnd(temp,current); * There is an error in this code. you should assign *temp=rslt* so that current is added to the DLL rslt. In your code, it just assigns current to rslt whereas it should append current to rslt. That is why in the end 4 is assigned to rslt and it is the final value of rslt. So please make it: *temp=rslt; current=head; rslt=appnd(temp,current);* -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.
