for i in range(len(A)):
    min_= i
    for j in range(i+1, len(A)):

#Output:

for i in range(len(A)):
    min_= i
    for j in range(i+1, len(A)):

    A[i], A[min_] = A[min_], A[i]
# main

for i in range(len(A)):
    min_= i
    for j in range(i+1, len(A)):
        if A[min_] > A[j]:

    #swap
    A[i], A[min_] = A[min_], A[i]
# main
for i in range(len(A)):
    print(A[i])
