看着很复杂的一道模拟题,虽然写起来确实不怎么复杂,但细节还是比较多的. 主要分析的就是-的处理情况,总体上就是展开和不展开(直接输出)的判断. 需要展开的情况: 前后有字符,且均为字母或数字 字符后者-前者的ascii值>=1 (=1时仍然是展开,但什么都不输出.我是用了个特判,但想想好像也不需要) 那么不展开的情况就是非上述情况了.包括首尾,前后不为相同类型,甚至还有一堆-相连的一个测试点 我还纳闷为啥还有90分这种情况 总体上还是判断写的太渣了,但我又懒得改,开摆! AC代码 欢迎加入团队

非常好的一道模拟题。 纯模拟就行，把脑子拿出来寄存一下，然后无脑模拟就行。

影响输出的是p1和p3,p2其实无关紧要，只要在循环输出的时候作为边界即可。

一个if，写了四行 很长的if,在我的编辑栏里长四行
