C++ Exercises: Move the first two characters to the end of a given string of length at least two

C++ Basic Algorithm: Exercise-65 with Solution

Write a C++ program to move the first two characters to the end of a given string of length at least two.

Sample Solution:

C++ Code :

#include <iostream> // Including the input/output stream library

using namespace std; // Using the standard namespace

// Function that manipulates input string and returns a modified string
string test(string s1)
{
    string s2 = s1; // Declaring and assigning s2 as a copy of s1
    return s1.erase(0, 2) + s2.substr(0, 2); // Erase the first two characters of s1 and concatenate them with the first two characters of s2
}

// Main function
int main()
{
    cout << test("Hello") << endl; // Output the result of test function with "Hello"
    cout << test("JS") << endl;    // Output the result of test function with "JS"
    return 0; // Return statement indicating successful termination of the program
}

Sample Output:
