// Sort String Descending with Reverse Iterators
#include <iostream>
#include <string>    // Required for std::string
#include <algorithm> // Required for std::sort
using namespace std;

int main() {
    // Step 1: Initialize the string
    string myString = "programming";
    cout << "Original string: " << myString << endl;

    // Step 2: Sort the string in descending order using reverse iterators
    // std::rbegin() gives a reverse iterator to the last element.
    // std::rend() gives a reverse iterator to the element before the first.
    // std::sort sorts the range in ascending order of the reverse traversal,
    // which effectively sorts the original string in descending order.
    std::sort(myString.rbegin(), myString.rend());

    // Step 3: Print the sorted string
    cout << "Sorted string (descending): " << myString << endl;

    return 0;
