Why test case number 8 is hidden in password validation challenge..

Question

#include <bits/stdc++.h>
using namespace std;
void ps(string s){
int i,j=0;

if(s.length()<7){
cout<<"Weak";
return;
}
for(i=0;i<s.length();i++){
if(isdigit(s[i]) || ispunct(s[i])){
j++;
if(j>=4){
cout<<"Strong";
return;

}
}

}

cout<<"Weak";
return;

}
int main() {
string s;
cin>>s;
ps(s);

return 0;
}

this is my code for that problem
its a code coach problem
only 1 test case is not getting passed what is wrong I'm not understanding?

Answer 1

Your approach is wrong. The problem states that the password is valid (strong) if it has atleast two numbers and atleast two punctuations and is atleast 7 characters long. But according to your code it will print strong when there will be either 4 numbers or 4 punctuations.
