Andy 是个 8 岁的孩子,他梦想要制作一本他自己的字典. 这并不是一件容易的事,因为他认识的字还不是那么多. 他并不想要自己去想这本字典中该放哪些字,他有个聪明的主意. 就是拿出他最喜欢的一本故事书,从那里面挑出所有不同的字来,然后按照字典数序列出. 当然,对他来说这是一件相当花时间的工作,所以你被要求写一个程序来帮助他. 在这个问题中,一个字被定义为一连续字母所组成的字符串. 并且,你的程序应该是不管字母大小写的. 例如: "Apple", "apple",…

感觉这道题要比之前几个字符串处理的题目难度要大了一些. 题目大意:给若干行字符串,提取出所有单词并去掉重复的,最后按字典顺序输出. 对于输入大致有两种思路,一种是逐个读入字符,遇到字母的话就放到word里面,直到遇到非字母字符,在word最后放'\0'. 我采用第二种思路,就是用gets()函数逐行读到str字符数组里面,然后逐个把单词提取出来. Count存放的是Dictionary里单词的个数,每提取一个单词,看看Dictionary里有没有该单词,没有的话放到字典里面,并且计数器加1. 由…

(我恨字符串) 惯例化简题目:给定n个字符串,可以改变字符的相对大小(在字典序中的大小),问:字符串i是否能成为最小的字符串(字典序) 解题过程: 首先你可以预处理出来26的全排列然后暴力然后你只要用神威太湖之光开O2就能过了 秒切字典树 推出一堆没用的结论. 说一下思考过程:首先字典树能找前缀都知道吧 观察样例,得:对于不能变成第一的,那么一定是有一个跟它有相同前缀的字符串,但是不完全相等,要有比当前串小的. 然后和旁边大佬一起歪歪瞎搞:建立一棵字典树,然后对于每个字符串跑一遍字典树,如果能找…
