选择排序法。用选择排序法将N（N为5）个数从小到大排序后输出。 **输入格式要求："%d"+提示信息："Enter+No.%2d:" **输出格式要求："%d" 程序运行示例如下： Enter+No.

def selection_sort(arr):
    n = len(arr)
    for i in range(n):
        min_idx = i
        for j in range(i+1, n):
            if arr[j] < arr[min_idx]:
                min_idx = j
        arr[i], arr[min_idx] = arr[min_idx], arr[i]

arr = []
for i in range(5):
    num = int(input("Enter No.%2d: " % (i+1)))
    arr.append(num)

selection_sort(arr)
for num in arr:
    print(num)
