输入在4行中分别给出4个非空、不包含空格、且长度不超过60的字符串。
在一行中输出约会的时间，格式为“DAY HH:MM”，其中“DAY”是某星期的3字符缩写，即MON表示星期一，TUE表示星期二，WED表示星期三，THU表示星期
四，FRI表示星期五，SAT表示星期六，SUN表示星期日。题目输入保证每个测试存在唯一解。

* 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”
* 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
*
* 注意点：1.要对应位置的字符相同才算成对，2.注意序列长度不同，3.注意三个元素的判定依据
