Problem Statement

Write a C++ recursive function to check whether a given string is a palindrome.

Input Format

A single word string S.

Output Format

Print 'Palindrome' or 'Not Palindrome'.

Constraints

1 <= Length <= 50

Sample Input

racecar

Sample Output

Palindrome

Explanation

Compares outer characters and recurses inward towards the center.

Starter Code

#include <iostream>
#include <string>

bool isPalindrome(const std::string& s, int low, int high) {
    // Write your code here
}

int main() {
    std::string s;
    if (std::cin >> s) {
        if (isPalindrome(s, 0, s.length() - 1)) std::cout << "Palindromen";
        else std::cout << "Not Palindromen";
    }
    return 0;
}

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
