1358:中缀表达式值(expr)
【题目描述】 输入一个中缀表达式(由0-9组成的运算数、加+减-乘*除/四种运算符、左右小括号组成。注意“-”也可作为负数的标志,表达式以“@”作为结束符),判断表达式是否合法,如果不合法,请输出“NO”;否则请把表达式转换成后缀形式,再求出后缀表达式的值并输出。 注意:必须用栈操作,不能Period [HDU 1358]
题目: For each prefix of a given string S with N characters (each character has an ASCII code between 97 and 126, inclusive), we want to know whether the prefix is a periodic string. That is, for each i (2 <= i <= N) we want to know the largest K >厦大C语言上机 1358 小明的考题3――必杀技

题意:给定一个字符串,问这个字符串的所有前缀中,前缀最多重复的次数k,这个k需要大于1。 KMP最小循环节、循环周期: 定理:假设S的长度为len,则S存在最小循环节, 循环节的长度L为len-next[len],子串为S[0…len-next[len]-1]。 (1)如果len可以被len - next[len]整除, 则表明字符串S可以完全由循[LeetCode] 1358. Number of Substrings Containing All Three Characters
