PROBLEM

Given string as a password. Check if it satisfies following conditions.

• Length is at least 5 characters.
• At least one Large English letter.
• At least one small English letter.
• It should contain at least one digit.

If String Satifies all the Conditions, print "YES" else print "NO".

EXPLANATION

Problem is Straight forward. Just correctly implement what was written in statement.

C++ Code:

#include<iostream>
#include<set>
using namespace std;
string s;
cin >> s;
bool upper = false, lower = false, digit = false;
for(int i= 0; i < s.size(); ++i){
    if(isupper(s[i]))
        upper = true;
    if(islower(s[i]))
        lower = true;
    if(isdigit(s[i]))
        digit = true;
}
puts((upper && lower && digit && s.size() >= 5) ? "YES" : "NO");

COMPLEXITY:

O(N)
