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:

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<simplecpp>
main_program{
int n;
cin>>n;
int a[n];
for(int i=0;i<n;i++)
{cin>>a[i];}


for(int i=0;i<n-1;i++)
{int temp;
 for(int j=i+1;j<n;j++)
 
 {if( a[i]>a[j])
 {int temp=a[j];
 a[j]=a[i];
 a[i]=temp;
 
 
 }
 
 
 }
 
 
 }cout<<temp;
 }

Grading criterion: Overall program correctness
Rating A: "Common requirements  of a Program are correct - i.e.
 
- header (includes, using namespace, etc)
- main syntax
- variables declaration
- overall syntax"
Rating B: Problems are present in the code(eg: printing unnecessary strings, missing semicolons & braces, wrong/missing declarations, wrong header files)
Rating C: 0
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
