Given an unsorted array of size N, use selection sort to sort arr[] in increasing order.

Example 1:

Input:
N = 5
arr[] = {4, 1, 3, 9, 7}
Output:
1 3 4 7 9
Explanation:
Maintain sorted (in bold) and unsorted subarrays.
Select 1. Array becomes 1 4 3 9 7.
Select 3. Array becomes 1 3 4 9 7.
Select 4. Array becomes 1 3 4 9 7.
Select 7. Array becomes 1 3 4 7 9.
Select 9. Array becomes 1 3 4 7 9.

Example 2:

Input:
N = 10
arr[] = {10, 9, 8, 7, 6, 5, 4, 3, 2, 1}
Output:
1 2 3 4 5 6 7 8 9 10

Your Task:  
You dont need to read input or print anything. Complete the functions select() and selectionSort() ,where select() takes arr[] and starting point of unsorted array i as input parameters and returns the selected element for each iteration in selection sort, and selectionSort() takes the array and it's size and sorts the array.

Expected Time Complexity: O(N²)
Expected Auxiliary Space: O(1)

Constraints:
1 ≤ N ≤ 10^3
