Codechef Problems: Fonta (FONTA)

 

Problem Statement:

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

Solution:

Given,

A drink is called fanta-like if it has its last 3 characters ‘nta’

Condition, it is guaranteed that input string has 5 characters

To find, whether the input string is fanta-like or not

 

To solve this problem we first need to check whether the input string has five characters or not

Condition : If length of input string is not 5

Output : NO

 

After this we need to find whether the input string has last three characters ‘n’, ‘t’ and ‘a’ respectively

Condition 1 : If last 3^rd character = n and last 2^nd character = t and last character = a

Output : YES

Condition 2 : otherwise

Output : NO

 

Code Solution:

#include <bits/stdc++.h>

using namespace std;

int main() {

    string str;

    cin >> str;

    if (str.length() != 5) {

        cout << "NO" << endl;

        return 0;

    }

    if (str[2] == 'n' && str[3] == 't' && str[4] == 'a') {

        cout << "YES" << endl;

    } else {

        cout << "NO" << endl;

    }

    return 0;

}
