Re: [algogeeks] How will you implement a stack using a priority queue. Push and pop should be in O(1)
you are doing it correct.

I am not getting the y priority Q is getting used for this question, as in
case of P Queue, things are arranged as per the priority so when we will
insert the data we can simply increament the priority.
Algo would be like this :
Enque(q, data) {
push(q, data, increrase the prioroty);
}
int Deque() {
return pop();
}
here higher priority one shuld be poped first.
PLEASE SUGGEST if any good approach some one is having other than this ?

Ans to *Boundary traversal of a tree. Write the code.
*1) you need to for preoder oder for left most tree with flag and post
order traversal for right most tree with flag.
2) the role of flag would be to decide wther to print or not like in case
of left subtree ,flag would be tree as u knw that
in preorder traversal left element would be boundary and once u go
right make it false .. same for right subtree:
Code snippet would look like this :
void printleft (struct node *root, bool flag) {
if (!root) return;
if (flag || (!root-left !root-right)) {
cout root-data;
}
printleft(root-left, true);
printleft(root-right, false);
}
this is preorder for left subtree , do post order for right subtree like :
void printright (struct node *root, bool flag) {
if (!root) return;
printright(root-left, false);
printright(root-right, true);
if (flag || (!root-left !root-right)) cout root-data;

Re: [algogeeks] help with o/p why 0 comes???
yup , it is showing

0
on ideone as well . so my gcc compiler is i686-apple-darwin11-llvm-gcc-4.2.
that can be the reason . from here it appears 0 is just a coincidence and
it depends on compiler implementation . C doesn't define any such behavior.

Re: [algogeeks] Re: Algo Question
take this example
let the gaurds demand be
5 2 7 2 9
first guard : we have no choice but to give him 5
second guard : we have choice , either skip him and pay 7 to next guard or
pay him and save 7 from third guard .. thus clearly multiple solutions
exist but we have to give optimal one. { hint for dp }
if we know the solution for upto i-th guard, we can extend this solution to
i+1-th guard
solution here represents all the possible amounts that one can spend till
i-th guard, extending that will give us all the possible amounts for i+1 th
guard and we just select the minimum amount. thus optimal substructure is
also there.
using the below code , the output for example is 12 with possible sequence.
guard 1 : 5
guard 2 : skip
guard 3 : 7
guard 4 :skip
guard 5 :skip
// non optimized code -purely for demonstration purpose -
#include stdio.h
#include stdarg.h
#define size 5
#define amount 1000 // maximum amount asked by all the gaurds combined
int solution[size][amount];
int main (int argc, char const *argv[])
{
int arr[] = {5,2,7,2,9};
int min, i, j;
int sum = 0;
for(i = 0; isize; i++) {
sum += arr[i];
}
solution[0][arr[0]] = 1;
for(i = 1; i size; i++) {
for(j = 0; j= sum; j++) {
if(solution[i-1][j] == 1) {
if(j arr[i]) {
solution[i][j] = 1;
}
solution[i][j + arr[i]] = 1;
}
}
}
min = 10; // infinite value
for(i = 0; i sum; i++) {
if(solution[size - 1][i] i min)
min = i;
}
printf(%d, min);
return 0;
}
@marti check the solution for other testcases , I'll post the optimized
version after that.

Re: [algogeeks] C output
for a 32 bit it is 4 ,3 and for 16 bit it is 2,3 and 64 bit it is 8,3.. also strlen(d) gives 3 bcz the coding of fn strlen() is such that as it encounters null it will terminate..so irrespective of machine it prints 3 as null at 4th place -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Re: [algogeeks] Kth largest element
Okay. We can do it with min Heap. 1) Build a Min Heap MH of the first k elements (arr[0] to arr[k-1]) of the given array. O(k) 2) For each element, after the kth element (arr[k] to arr[n-1]), compare it with root of MH. a) If the element is greater than the root then make it root and call heapify http://www.personal.kent.edu/%7Ermuhamma/Algorithms/MyAlgorithms/Sorting/heapSort.htmfor MH b) Else ignore it. O((n-k)*logk) 3) Finally, MH has k largest elements and root of the MH is the kth largest element.

Re: [algogeeks] Re: Static variable
while(--i 0) //suppose i = 1 here, so --i becomes 0, hence the condition
fails...so it will go 1 step back in recursion
{
main();
printf(%d,i);
}
it will execute
printf(%d,i) of prev recursion where i=0 now, so 0 gets printed...now
again the condition is checked i=0, thrfore --i becomes -1, so condition
fails
it now executes printf(%d,i) of still prev recursion and i=-1 herethis
continues...
I hope this clarifies

The problem is to determine if there is a loop. That means there might
not be. And if there isn't, you really shouldn't dump core.

Re: [algogeeks] Re: How to hash Strings
Well I came across a great hashing algorithm, known as djb2 hash for hashing
strings..would like to share it:
int get_hash(char *s)
{
int hash = 0;
while(c = *s++)
{
hash = ((hash 5) + hash) ^ c;
}
return hash;
}
this can be done for each individual string to be hashed..

Pointer incrementation and subtraction are done in terms of memory blocks
and not addresses of memory.
For example,
int *p;
p++;
The pointer here jumps to the next integer location and not the next address
in memory.
Similarly,pointer subtraction will give the difference in indexes and not
the memory addresses.
If you try subtracting an integer pointer and a float pointer, it will be an
error.

Re: [algogeeks]
@aditya . (int*)0 is pointing to Null value , so (int*)0+1 will be 0x4 which is the size of int as implemented in compiler . so basically your code is returning sizeof(int) which will always return 4 which is equivalent to 32 bits . I couldn't check this program on a 64 bit machine ( p.s. mine support 64 bit but the OS is 32 bit ) but I guess it will return 32 on 64 bit machine as well I may be wrong, so If you have run this code and found 64 than let me know.

@aditi For the first question. The answer will be ((0.97 *2) + (0.03*2) +(0.03*100)) i.e 5 ns.

[algogeeks] Re: Doubts
In memory heirachy, whenever some data is to be read, first data is to be searched in M1, if the data is found in M1 then system returns the value from there and counted as a hit. If the value is not found in M1 i.e. Miss for M1 then it accesses M2 and returns the value from there. Since nothing is given about miss in M2, I am assuming that it is the main memory and there is no miss there. -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Re: [algogeeks] Re: Doubts
@aditi since in the hierarchy m1 comes first so if it is a hit then we dont need to check m2 but in case of a miss 0.03*2 seconds are wasted while searching in m1 then that value is looked for in m2 so i suppose the best answer is given by rohit jain. unless there is some missing data On Tue, Aug 9, 2011 at 5:41 PM, aditi garg aditi.garg.6...@gmail.comwrote: @Rohit: we wont include the miss time fr M2 then?

[algogeeks] Re: n-ary tree
use a linked list to store child nodes, a tree node will hold pointer
to next sibling and a pointer to its first child.
typedef struct TreeNode{
struct TreeNode * nextSibling;
struct TreeNode * fistChild;
//rest things
}

you might get error: floating pointing formats not linked!!

otherwise code written by Dipankar will solve ur problem if u r unable to

There is always some problem in string input using %s, don't really know

Re: [algogeeks] Question
try using dev or any new 32bit compiler it wont give that error!!!
or try using this
void linkfloat(void)
{
float a=0,*b=a;
a=*b;
}
this code forces the emulator to be linked

Re: [algogeeks] merging of two sorted arrays

int i=n-1;
int j=m-1;
