Codechef Problems: Snaky Strings (SSNK)

 Problem Statement:

https://www.codechef.com/problems/SSNK

Solution:

Given, a string is called ‘snaky’ if it starts or ends with the letter ‘s’

                Input string is of length 4

To find, whether the input string is snaky or not

 

To solve the above problem first we need to check whether the input string has length 4 or not

Condition : length of input string is not 4

Output : NO

 

Then, we need to find whether the string starts or ends with letter ‘s’

Condition 1 : string[0] == ‘s’ or string[3] == ‘s’

Output: YES

Condition 2 : otherwise

Output: NO

 

Code Output:

#include <bits/stdc++.h>

using namespace std;

int main() {

    string str;

    cin >> str;

    if (str.length() != 4) {

        cout << "No" << endl;

    }

    if (str[0] == 's' || str[3] == 's') {

        cout << "Yes" << endl;

    } else {

        cout << "No" << endl;

    }

    return 0;

}
