Re: [algogeeks] Google Interview Question: In how many intervals does a number exists
2-2 as 2 lies in [2,3] and [1,4] ?

There are n Intervals. Given a set of m numbers, tell in how many
intervals does each number exists.
Example: 4 Intervals: [2,3] [3,4] [1,4] [3,10]. Numbers {2,4,11}
For 2 - 1 as 2 lies only in 1 interval [2,3]
For 4 - 3 as 4 lies in 3 intervals
For 11 - 0 as 11 lies in none of the given 4 intervals.
It can be easily done in O(m*n) by traversing n intervals for each number
in the given set of m numbers. How would improve this?
Note: I could not fully recall, but I have seen very similar question in
codechef but could not find the same.

Re: [algogeeks] Google Interview Question: In how many intervals does a number exists
Read up on Interval trees http://en.wikipedia.org/wiki/Interval_tree.
Programmers should realize their critical importance and responsibility in
a world gone digital. They are in many ways similar to the priests and
monks of Europe's Dark Ages; they are the only ones with the training and
insight to read and interpret the scripture of this age.

Re: [algogeeks] Google interview question
thats the challenge man ! if u are declaring a static Array of 2GB and u might find the repeated element in second step then memory is waste ! Thats why hashing ! hashing has complexity of O(n) only !

Re: [algogeeks] Google Interview Question
@Bhavesh:
Counter case for you:
array = {68, 6867}
u change this array to: {6866, 6867}
then u sort them to get 6867, 6866 and then give the ans as: 686768. While
the correct ans is: 686867
The problem in ur algo is in appending the first digit at the end of each
number. For a correct algo, not just the first digit but the complete number
should be appended.
Hence, to get correct result, you should change the array to : {6868, 6867}.
Hope this makes things clear for you.

Re: [algogeeks] Google Interview Question
i guess Sunny has already mentioned (concatenating the two numbers and
comparing) this technique before, i liked and tried coding it ... it works
perfectly without comparing the second digit incase the first is same. the
algorithm can run in O(nlogn) taking the best sorting technique , though i
have used the O(n^2)one.
i tried for 5 numbers, one can do it for N numbers too.
@maksym could you explain your logic
int length(int );
int power(int );
int com(int, int );
void swap(int *, int *);
main()
{
int a[5],l, j, temp;
int i ;
for(i = 0 ;i5;i++)
{
printf( \n\tEnter the %d number , i+1);
scanf(%d,a[i]);
l =length(a[i]);
}
for (i = 0; i5; i++)
for (j = 0 ; j5;j++)
{
temp = com(a[i], a[j]);
if (temp != a[i])
swap(a+i, a+j);
}
for (i = 0 ;i5;i++)
printf(\n\t%d,a[i]);
printf(\n\t\t The largest possible number is\n\t );
for (i = 4 ;i=0;i--)
printf(%d,a[i]);
getch();
}
void swap(int *n1, int *n2)
{
int temp;
temp = *n1;
*n1 = *n2;
*n2 = temp;
}
int length(int a)
{
int len=0,i = 10 ;
while (a!=0)
{
a = a/10;
len++;
}
return len;
}
int com(int a1, int a2)
{
int l1, l2;
int c,d;
l1 = length(a1);
l2 = length(a2);
c= a1*power(l2) +a2;
d = a2*power(l1)+a1;

Re: [algogeeks] Google Interview Question
@ Maksym Melnychok Fails i think some explanation say we have numbers 1 , 101 divide all by something to get 0.1, 0.101 simple sort will give you 0.101, 0.1 multiply all numbers to get original ones 101,1 join 1011 but correct answer should be 1101, isn't it ?? correct me if i m wrong ?? -- Sunny Aggrawal B-Tech IV year,CSI Indian Institute Of Technology,Roorkee -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Re: [algogeeks] Google Interview Question
possible fix for 100 10 edgecases would be to simply array.map{|x| x*10+1}
and then get rid of that after sorting

Re: [algogeeks] Google Interview Question
solution may be
array ={ 3 ,21 ,9 ,93,17 ,178 ,1,101} (i think i have covered all exceptions
)
then ,change this array like 3 , 21222, 9, 93999, 17111, 17811,
1 , 10111 ( make each number of 5 digit with rest digits same as Ist
digit )
then sort this array
9, 93999,3 21222, 17811,17111, 1, 10111
and make it with actual numbers
9,93,3,21,178,17,1,101= 993321178171101
plz let me know if any case left...

Re: [algogeeks] Google Interview Question
Can this work...
Lets say I have following numbers
8 9 7 4 2 121 23 21 24 27 35 79 2334 6785
Now repeat the last number to make all the number of equal length...
1211 2333 2111 2444 2777 3555 7999 2334 6785
Sort the following numbers in descending order.
7999 6785 ...
Now merge the numbers based on their actual value.
987976785..
I have not testing this entirely, but after seeing solution(Multiplying by
10) at top, I though this might work better.

how about this case: 9, 100 - 9100 100 9 9100 2, 3, 9, 78 -- 78 9 3 2 9 78 3 2 I guess solution should be:- sort the array of numbers in an ascending order and then check for the first element in the array, if there is any other element greater than it, shift all the elements one right and place that element in the left most space.

how about adding zeroes at the end of integers to make to equal to the integer with maximum number of digits and sort them... ex- 101 10 adding zeroes.. 101 100 sort 100 101 therefore make number as 10110 100 1 adding zeroes 100 100 therefore number is 1100 I am not sure of the method.if there is any counter case please do suggest...

check whether these steps work: step 1: sort the given numbers in the decreasing order based on their first digit. step 2: if two numbers come out to be equal in the above case both of their next digit exist then sort on the basis of their next digit, otherwise the number whose next digit doesnot exist should be placed before the other number. step 3: concatenate these numbers. e.g. (0,1,10,100) sorting it gives: 1,10,100,0 = 1101000 (97,8,9) sorting gives: 9,97,8 = 9978 correct me if i'm wrong.

Re: [algogeeks] GOOGLE INTERVIEW QUESTION
Hello Anders Ma .. for inputs like iiestseig (just a random string) your
code will not produce the correct output .. cos the best possible way to
split these strings is {i,iestsei,g} .. But your code will produce
{ii,este,i,g} as output .. so when there are overlapping palindromes
your code wont produce the correct output .. please look into it ..

Re: [algogeeks] Google Interview Question
There might be some error in calculating the value of some variable(s) which might be used to retrieve elements in some arrays/maintaining stack/linked list or any other data structure that uses the value of that variable to retrieve information from memory. Carefully checking the values of variables that are used to allocate/deallocate or retrieve memory contents can be helpful.

@ pacific: Also consider the choice of flipping the node itself. And if an internal node cannot be flipped, it is still possible to flip its value, only the above choice is not taken into consideration..

Re: [algogeeks] Google Interview Question
here is my approach : Starting from the root node , if root node need to have a 1 ... if root is an and gate : flips = minflips for left child to have value 1 + minflips for the right child to have value 1 else flips = minimum of ( minflips for left child to have value 1 , minflips for right child to have value 1) For a leaf node , return 0 if the leaf has the value needed else return INFINITY.Also if at any internal node if it is not possible return INFINITY.

Re: [algogeeks] Google interview question
i have a one idea in my mind is to implement a hash table structure based on
26 alphabets
and a data structure of words.
struct word
{
int info;
char a[n];
};
structure contains the info about the word and an array in which document
it is present or not out of n
ex if it is word is mnnit and it is in document 1 ,4,6,9
the info of the structure would be char[1,4,6,9]=1
and the rest are zero.
insertion of word would take o(1) time but searching would take o(n) time if
list is implemented as an array list
and if implemented as an binary search tree would take it log(n) but than
insertion would also take log(n) time

Hi,
suppose we have given n distinct numbers are a[n].
1. sort them using quick or any other sort in O(nlogn)
2. use then
int find(int *arr, int n) /* return largest number if fing it otheriwse
retirn 0*/
{
int i,j,k, temp;
for(k=n-1; k2;k--)
{
j = k-1
i=0;
while(i!=j)
{
temp = arr[i]+arr[j];
if(temp== arr[k])
return arr[k];
else if(temparr[k])
i++;
else
j--;
}
}
return 0;
}
