Run time eroor on CB IDE

#1

I have submitted my solution
#include
#include<bits/stdc++.h>
using namespace std;
int main()
{
string s;
cin>>s;
int len=s.size();
int f[1005];
for(int i=0;i<len;i++)
{
int cs=1;
for(int j=i+1;j<len;j++)
{
if(s[j]==s[i])
{
cs++;
}
}
f[i]=cs;
}
int max1=f[0];
int ans;
for(int i=0;i<len;i++)
{
if(f[i]>max1)
{
max1=f[i];
ans=i;
}
}
cout<<s[ans];
return 0;
}
this to problem MAX FREQUENCY CHARACTER and i am getting run time error in three cases in CB IDE whereas in other IDE’s it is working perfect.
Please tell my mistake;
