课后题20,动动手第一题,找密码

本帖最后由 shenshuai 于 2019-10-14 07:39 编辑

各位大佬们,我看了论坛里的一些朋友发的这道题答案之后我还是有些点不是很理解。希望大佬们能帮忙解释一些,谢谢了。

原题目问题:
1. 请用已学过的知识编写程序,找出小甲鱼藏在下边这个长字符串中的密码,密码的埋藏点符合以下规律:Y5d|MAp
Y5d|MAp
    a) 每位密码为单个小写字母
    b) 每位密码的左右两边均有且只有三个大写字母

以下是我看的其他朋友的答案,有些地方不是很理解。

水平不够,只能帮题主提供一些思路
108行i赋值为3应该是使得后面的while循环和if条件判定成立吧(题主可以试试改成其他数,看看程序有什么变化)
