Grading criterion: Correctness of finding index of initial minimum value
Rating A: Correct index is calculated
Rating B: Index calculated is wrong
Rating C: 0
Rating D: 0
Assigned grade: B
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.

Constraints:

* n < 25

Input Format:

* Non-negative integer n
* Array A of n elements

Output Format:

* Print the sorted array with a space between adjacent elements.

Student submission:
