﻿ C++ : Sort a list of numbers using Bogo sort algorithm

# C++ Bogosort algorithm Exercise: Sort a list of numbers using Bogosort algorithm

## C++ Sorting: Exercise-3 with Solution

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
```
