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:
#include<iostream>
using namespace std;
void myswap(int* a, int& b){
  int temp =a ; a =b ; b= temp;
  return;
}
int main()
{
   int n;
   cin>>n;
   int A[n];
   for(int i=0; i<n;i++) { cin>>A[i];}
   int min=0
   for(int j=0; j<n; j++) 
   {
      if(a[j] < a[j+1]) {min=a[j];}
   }
   for(int x=0;x<n;x++) { myswap(a[i],min);}
   for(int y=0;y<n;y++) {cout << a[y] ;}
}

Grading criterion: Correctness of loop for iteratively swapping elements of sub-array with the minimum elements
Rating A: The loop traverses through the array correctly swapping all the minimum elements with the first index
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
