Getting W.A. Whats the problem?
#include<string.h>
#include<stdio.h>
int main()
{
char key[]={'`','1','2','3','4','5','6','7','8','9','0','-','=','\\','Q','W','E','R','T','Y','U','I','O','P','[',']','A','S','D','F','G','H','J','K','L',';','\'','Z','X','C','V','B','N','M ...

Thank you very much. I got it accepted.

How can I stop this? I am weak in these case.

My code is giving all the output correctly. But I am getting WA. Please help anyone..

What is wrong?
#include<stdio.h>
#include<math.h>
#define len 10000000
char prime[len+1];
void sieve()
{
int i,j,k=0,r;
prime[0]=prime[1]=0;
prime[2]=1;
for(i=3;i<=len;i+=2)
{
prime[i]=1;
prime[i+1]=0;
}
r=(int)sqrt(len);
for(i=3;i<=r;i++)
{
if(prime[i]==1)
{
for(j=i*i;j<=len;j+=i*2 ...

Please anyone help me. :x
Here is my code. I got WA again and again.

Thank you very much.
I got it.

I wrote this code. output cases were correct . but WA. :x
#include<stdio.h>
int main()
{
int i,j,x,y,m,field=1;
char mine[110][110];
while(scanf("%d%d",&x,&y)==2)
{
if(x==0&&y==0)break;
for(i=0;i<x;i++)
{
for(j=0;j<y;j++)
{
scanf("%1s",&mine [j]);
}
}
if(field>1) printf("\n");
printf ...

I submitted this code. But got WA. Con u help me?
#include<stdio.h>
long double fact(long double n)
{
if (n==0) return 1;
else return (n*fact(n-1));
}

int main()
{
long double n,k,r,f,g,temp;
while(scanf("%Lf%Lf",&n,&k)==2)
{
long double u=1,l1=1,l2=1;
if(n==0 && k==0) break;

f=fact(n ...

I gave this solution for prob-10235. But it made WRONG ANSWER. Where is the fault?
#include<stdio.h>
long int prime(long int n){
int i,a=0;
for(i=2;i<=n/2;i++){
if(n%i==0) {
a++;
break;
}
}
if(a>0) return 0;
else return 1;
}
long int reverse(long int n)
{
long int x,rev=0;
while(n>0 ...
