717. 1比特与2比特字符 LeetCode717. 1-bit and 2-bit Characters 题目描述 有两种特殊字符.第一种字符可以用一比特0来表示.第二种字符可以用两比特(10 或 11)来表示. 现给一个由若干比特组成的字符串.问最后一个字符是否必定为一个一比特字符.给定的字符串总是由0结束. 示例 1: 输入: bits = [1, 0, 0] 输出: True 解释: 唯一的编码方式是一个两比特字符和一个一比特字符.所以最后一个字符是一比特字符. 示例 2: 输入: b…

这是悦乐书的第302次更新,第321篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第170题(顺位题号是717).有两个特殊字符,第一个字符可以用一个比特0表示,第二个字符可以用两个比特(10或11)表示.现在给出一个由比特位组成的数组,判断其最后一个字符是否是一位字符.数组的最后一位始终是比特0.例如: 输入:bits = [1,0,0] 输出:true 说明:解码它的唯一方法是两位字符和一位字符,所以最后一个字符是一位字符. 输入:bits = [1,1,1,0…
