DIFFICULTY:
EASY.
PROBLEM:
Chef has a number N, Cheffina challenges the chef to check the divisibility of all the permutation of N by 5. If any of the permutations is divisible by 5 then print 1 else print 0.
Program:
#include<bits/stdc++.h>
using namespace std;
int main()
{
ios_base::sync_with_stdio(false);
cin.tie(NULL);
cout.tie(NULL);
int t,n;
cin>>t;
while(t--){
string s;
cin>>s;
bool f=false;
for(int i=0;i<s.length();i++)if(s[i]=='0'||s[i]=='5'){
f=true;
break;
}
if(f)cout<<1<<"\n";
else cout<<0<<"\n";
}
}
