Can you solve this real interview question? String Compression - Given an array of characters chars, compress it using the following algorithm: Begin with an empty string s. For each group of consecutive repeating characters in chars: * If the group's
Given an array of characters, compress itin-place. The length after compression must always be smaller than or equal to the original array. Every element of the array should be a character (not int) of length 1. After you are done modifying the input arrayin-place, return the new length...
输入:["a"]输出: 返回1,输入数组的前1个字符应该是:["a"]说明: 没有任何字符串被替代。 示例3: 输入:["a","b","b","b","b","b","b","b","b","b","b","b","b"]输出: 返回4,输入数组的前4个字符应该是:["a","b","1","2"]。 说明: 由于字符"a"不重复,所以不会被压缩。
题目地址:https://leetcode-cn.com/problems/string-compression/ 题目内容: 给定一组字符,使用原地算法将其压缩。 压缩后的长度必须始终小于或等于原数组长度。 数组的每个元素应该是长度为1 的字符(不是 int 整数类型)。 在完成原地修改输入数组后,返回数组的新长度。 进阶: 你能否仅使用O(1) 空间解决问题?

注意,这道题和 Leetcode 上的 String Compression 很像,不过 Leetcode 上直接返回压缩后的字符串长度,其实本质上是一样的。给出的compress函数def compress(chars): pass 问题分析这个问题的考察点在于两点:能否做到原地变换(inplace) 能否做到使用 O(1) 的额外空间 首先,我们可以依次记录一下每个字符每次连续...
