Grading criterion: Correctness of loop for iteratively finding minimum elements of sub-array
Rating A: The loop traverses through the array correctly finding all the minimum elements correctly
Rating B: Partially correct loop for traversing through the array to find the minimum elements
Rating C: No loop or Totally wrong loop for traversing through the array
Rating D: 0
Assigned grade: A
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:
#include<iostream>
using namespace std;
int main()
{
int A[100],n,i,j;
cin>>n;
for(i=0;i<n;i++)
{
