[Python知识库]选择排序——Implemented by Python & Swift

Python

def selection_sort(array):
    for i in range(0, len(array) - 1):
        min_index = i
        for j in range(i + 1, len(array)):
            if array[j] < array[min_index]:
                min_index = j

n = int(input())
a = list(map(int, input().split()))

Swift

        a[i] = a[minIndex]
        a[minIndex] = temp
