very easy problem. just handle leading zeroes carefully. should be ac in less than 10 minutes .

[sms.islam]

Thanks.............finally i got AC...........thats a great feelings isn't it?

[naseef_07cuet]

It is a very simple problem.. Happy coding:)

[sumit saha shawon]

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;
}

Doesn't match the sample I/O.

plamplam, Shafaet_du,

Thanks for the great test cases!

[uDebug]

my all input and output correct but why I am getting wa ops

Look at Line #11 in your code

Code: Select all

scanf("%s",&ch);

This is probably something you do not want to do.

[axelblaze]

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;
}

[lighted]

is it because my output shows exponential numbers??

Yes. And not only for that reason. This line also won't work.

Code: Select all

double val=atof(ans);

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.

[axelblaze]

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..
