my all input and output correct but why I am getting wa
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]='\0';
if(ar[0]=='0')
{
i=0;
while(ar=='0')
i++;
if(i==a)
{
printf("0\n");
}
else
{
while(ar!='\0')
printf("%c",ar[i++]);
puts("");
}
}
else
{
for(i=0; ar!='\0'; i++)
printf("%c",ar);
puts("");
}
}
return 0;
}

ops
Look at Line #11 in your code
This is probably something you do
not want to do.

I've tested the Input's by plamplam & Shafaet_du but still getting WA. I have no Idea why...
is it because my output shows exponential numbers??
Code: Select all
#include<iostream>
#include<cstdio>
#include<cstring>
#include<cstdlib>
using namespace std;
int main()
{
//freopen("in.txt","r",stdin);
char num[110],c,ans[110];
while(cin>>c,cin.ignore(),cin.get(num,100),c!='0'||strcmp(num,"0"))
{
int j=0,length=strlen(num);
for(int i=0;i<length;i++)
if(num[i]!=c)
{
ans[j]=num[i];
j++;
}
ans[j]=0;
double val=atof(ans);
cout<<val<<endl;
}
return 0;
}

Yes. And not only for that reason. This line also won't work.
atof returns double value. Double can handle not more that 15 decimal digits of precision. But answer can be up 100 digits.
You can get accepted using c-string. Just remove flawed digit, avoid leading zeroes and print resulting string.

Thanks lighted but even now I'm getting WA. I've tested the input and it's works correctly...
here's my new code:
Code: Select all
#include<iostream>
#include<cstdio>
#include<cstring>
using namespace std;
int main()
{
//freopen("in.txt","r",stdin);
char num[110],c,ans[110];
while(cin>>c,cin.ignore(),cin.get(num,100),c!='0'||strcmp(num,"0"))
{
int j=0,length=strlen(num);
for(int i=0;i<length;i++)
if(num[i]!=c&&!(j==0&&num[i]=='0'))
{
ans[j]=num[i];
j++;
}
ans[j]=NULL;
if(ans[0]==NULL) {ans[0]='0';ans[1]=0;}
cout<<ans<<endl;
}
return 0;
}
by the way in case of "1 100000" the output is 0. but in my code::blocks on kubuntu 14.04 machine it shows an empty line. But in a windows machine it shows correctly.
Any Idea why?
I'm am new user of linux karnel so I have no clue.. It maybe is an off-topic but I need to know this. Thanks..
