Last update on December 20 2024 12:31:46 (UTC/GMT +8 hours)

Write a C++ program to sort a list of numbers using the Bogosort algorithm.

Sample Solution:

C++ Code :

// Including necessary C++ libraries
#include <algorithm>
#include <iostream>
#include <iterator>
#include <random>

// Function to perform bogo sort based on a custom predicate
template <typename RandomAccessIterator, typename Predicate>
void bogo_sort(RandomAccessIterator begin, RandomAccessIterator end,
               Predicate p) {
  // Random number generator setup
  std::random_device rd;
  std::mt19937 generator(rd());

  // Loop until the range [begin, end) is sorted
  while (!std::is_sorted(begin, end, p)) {
    // Shuffle the elements in the range using the random number generator
    std::shuffle(begin, end, generator);
  }
}

// Function to perform bogo sort using the default 'less' comparison
template <typename RandomAccessIterator>
void bogo_sort(RandomAccessIterator begin, RandomAccessIterator end) {
  // Utilizing the bogo_sort function with 'less' as the default comparison
  bogo_sort(
      begin, end,
      std::less<
          typename std::iterator_traits<RandomAccessIterator>::value_type>());
}

// Main function
int main() {
  // Initializing an array of integers for sorting
  int a[] = {125, 0, 695, 3, -256, -5, 214, 44, 55};

  // Displaying the original numbers in the array
  std::cout << "Original numbers:\n";
  std::copy(std::begin(a), std::end(a), std::ostream_iterator<int>(std::cout, " "));
  std::cout << "\n";

  // Sorting the array using bogo_sort function
  bogo_sort(std::begin(a), std::end(a));

  // Displaying the sorted numbers after bogo sort
  std::cout << "Sorted numbers:\n";
  std::copy(std::begin(a), std::end(a), std::ostream_iterator<int>(std::cout, " "));
  std::cout << "\n";

  // Returning 0 to indicate successful execution
  return 0;
}

Sample Output:

Original numbers:
125 0 695 3 -256 -5 214 44 55 
Sorted numbers:
-256 -5 0 3 44 55 125 214 695
