如下Python代码执行时如输入 5，将输出代码后的字符图形。

n = int(input())
for i in range(1, n + 1):
    for j in range(1, n - i + 1):
        print(0, end='')
    for k in range(1, 2 * i):
        if k <= i:
            print(k, end='')
        else:
            print(2 * i - k, end='')
    for j in range(1, n - i + 1):
        print(0, end='')
    print()
