Problem: Write a C++ program to sort an array A of n numbers strictly using the given algorithm:

1. Find the minimum element in the array.
2. Swap the minimum element with the first element of the array.
3. Find the minimum element in the remaining array.
4. Swap the minimum element with the second element of the array.
5. Repeat steps 3 and 4 until the entire array is sorted.

Rating B: Partially correct loop for traversing through the array to swap all the minimum elements with the first index
Rating C: No loop or Totally wrong loop for traversing through the array
Rating D: 0
Assigned grade: B
