This is working fine in my system and but it is showing runtime error.

int main(void)
unsigned int n,k,t;
int i,p=0;
scanf("%d %d",&n,&k);
{ scanf("%d",&t);
{ p++;

Hi deepika987,

Very first, please try pasting your code above in proper blocks or it’s always better to give the ideone link. The code is giving RTE because you haven’t added return 0; statement for main(). Add that and it’ll work.

Correctly format your code on give a link. Also provide details about the question you are trying to solve.

One problem with your code is that there is no return statement. Add a return(0) statement before the last braces.
