why getting wa???????????? :o

code:

#include<iostream>
#include<stdio.h>
#include<string.h>
#include<ctype.h>
#include<vector>
using namespace std;
char mes[10000];
int func(int n)
{
int a=0;
while(n)
{
a=a*10+(n%10);
n=n/10;

}
return a;
}
int main()
{

while(gets(mes))
{
vector<char ...

why getting wa?? :o
code:
#include<iostream>
#include<stdio.h>
#include<vector>
#include<queue>
using namespace std;
vector<int>v[100];
int ans;
void bfs(int src,int des)
{
queue<int>q;
q.push(src);
int taken[100]= {0},distance[100];
taken[src]=1;
distance[src]=0;
while(!q.empty())
{
int u ...

why I am getting WA??
My code:

#include<stdio.h>
#include<iostream>
#include<vector>
#include<queue>
#include<set>
#include<string.h>
using namespace std;
int main()
{
int edges;
int x,y;
int src,ttl,kase=1;
vector<int>G[100000];
set<int>s;

while(cin>>edges&&edges)
{
// cout<<edges<<endl ...

What is problem in my code???
My input output is ok.
code:
#include<stdio.h>
#include<string.h>
char str[50],ar[50],temp[50];
int main()
{
while(gets(str))
{
printf("%s",str);
int palindrome=0,mirror_strig=0;
int len=strlen(str),i,j=0;


for(i=0;i<len;i++)
temp =str ;
temp ='\0';
// puts ...

My all input and output is ok but why I am getting WA.
My code:

#include<stdio.h>
#include<string.h>
char field[105][105];
int main()
{
int r,c,a=1,kase=1;
while(scanf("%d %d",&r,&c)==2)
{
if(r==0&&c==0)
break;
// memset(field,0,)

int i,j,count=0;
for(i=0; i<r; i++)
scanf("%s",&field ...

my all input and output correct but why I am getting wa :oops:
My code:

#include<stdio.h>
#include<string.h>
char ch[1500],ar[1500];
int main()
{
int n;
while(scanf("%d",&n)==1)
{
if(n==0)
break;
scanf("%s",&ch);
int i,a=0;
for(i=0; ch !='\0'; i++)
{
if(ch -'0'!=n)
ar[a++]=ch ;
}
ar[a ...

where is bug in my code:

#include<stdio.h>
#include<math.h>
int prime[5000],k;
int list[5000];
void prime_num()

{
int a=5000;

int sq,i,j,str[5000]= {0};
sq=sqrt(a);
for(i=3; i<=sq; i+=2)
if(str ==0)
for(j=i*i; j<=a; j+=2*i)
str[j]=1;
prime[0]=2;
int x=1;
for(i=3; i<=a; i+=2)
if(str ==0 ...

Please give me a right logic to solve

thanks I have got AC

what is my problem?All of my input and output is ok.But I am getting WA. :x
my code is:

#include <stdio.h>
#include <string.h>
#include <ctype.h>
int main()
{
char str[3000],str1[3000],str2[30000];
while(gets(str))
{
int i,j,k,len;
if(strcmp(str,"DONE")==0)
break;
len=strlen(str);
for(i=0 ...

thanks so much I have got AC

I am asking for help but no one helping me.please help me

thanks I have got Ac

what is wrong with my algorithm:
#include<stdio.h>
#include<math.h>
int a[3050],k[3050];
int main()
{
int n,i,l,dif,y,j,temp;
while(scanf("%d",&n)==1)
{
y=0;
j=0;
// scanf("%d",&a[0]);
for(i=0;i<n;i++)
scanf("%d",&a );
for(i=0;i<n-1;i++)
{
temp=(a -a[i+1]);
if(temp<0)
temp=temp*(-1);
k ...

my output is ok but I am getting wa.please help me to find my bug
