题目描述:
大侦探福尔摩斯接到一张奇怪的字条:“我们约会吧! 3485djDkxh4hhGE 2984akDfkkkkggEdsb s&hgsfdk
d&Hyscvnm”。大侦探很快就明白了,字条上奇怪的乱码实际上就是约会的时间“星期四 14:04”,因为前面两字符串中第1对相同的大写英文字母(大小写有区分)是第4个字母’D’,代表星期四;第2对相同的字符是’E’,那是第5个英文字母,代表一天里的第14个钟头(于是一天的0点到23点由数字0到9、以及大写字母A到N表示);后面两字符串第1对相同的英文字母’s’出现在第4个位置(从0开始计数)上,代表第4分钟。现给定两对字符串,请帮助福尔摩斯解码得到约会的时间。
