Problem:
Selection Sort

Write a program of the Selection Sort algorithm which sorts a sequence A in ascending order. The algorithm should be based on the following pseudocode:

SelectionSort(A)
1 for i = 0 to A.length-1
2 mini = i
3 for j = i to A.length-1
4 if A[j] < A[mini]
5 mini = j
6 swap A[i] and A[mini]

Note that, indices for array elements are based on 0-origin.

Your program should also print the number of swap operations defined in line 6 of the pseudocode in the case where i ≠ mini.

Input

The first line of the input includes an integer N, the number of elements in the sequence.

In the second line, N elements of the sequence are given separated by space characters.

Output

The output consists of 2 lines.

In the first line, please print the sorted sequence. Two contiguous elements of the sequence should be separated by a space character.

In the second line, please print the number of swap operations.

Constraints

1 ≤ N ≤ 100

Solution in Python3 (judge verdict: Accepted)

def selection_sort(lis, l):
    times = 0
    for i in range(0, l - 1):
        minj = i
        minj_cp = minj
        for j in range(i, l):
            if lis[j] < lis[minj]:
                minj = j
        if minj_cp != minj:
            times += 1
        ele = lis[i]
        lis[i] = lis[minj]
        lis[minj] = ele
    return times

inputs = []
while True:
    try:
        inputs.append(input())
    except(EOFError):
        break

ln = int(inputs[0])
li = list(map(int, inputs[1].split()))

t = selection_sort(li, ln)

print(*li)
print(t)
