【JSCPC2021】Reverse the String(Lyndon 理论) 传送门题意给定字符串 ss,问任意翻转一个区间 [l,r][l,r] 后得到的最小字符串。∑|s|≤1.5×106∑|s|≤1.5×106。分析依次考虑答案第 ii 位能否比 sisi 小可得:ll 一定是右边有字符比它小的最左位置。因此只需考虑翻一个前缀的情况,可以用二分...
Does the strrev() modify the array into which the s points to? If yes, then the return value (a pointer) of the function has the same value as the input parameter s. If not, then the function must dynamically allocate memory for the C-string that it will return. ...
A word is defined as a sequence of non-space characters. Input string may contain leading or trailing spaces. However, your reversed string should not contain leading or trailing spaces. You need to reduce multiple spaces between two words to a single space in the reversed string. Follow up:...
Given an input string, reverse the string word by word. Example 1: Input:"the sky is blue" **Output: **"blue is sky the" Example 2: Input:" hello world! " **Output: **"world! hello"Explanation:Your reversed string should not contain leading or trailing spaces. Example 3: Input:"...
Reverse the strings in a string array and find strings that read the same when reversed. str = ["airport","control tower","radar","runway"] str =1x4 string"airport" "control tower" "radar" "runway" newStr = reverse(str) newStr =1x4 string"tropria" "rewot lortnoc" "radar" "yawn...
The string consists of lower English letters only. Length of the given string and k will in the range [1, 10000] 给定一个字符串和一个整数 k,你需要对从字符串开头算起的每个 2k 个字符的前k个字符进行反转。如果剩余少于 k 个字符,则将剩余的所有全部反转。如果有小于 2k 但大于或等于 k 个字符...
Write a function that reverses a string. The input string is given as an array of characterschar[]. Do not allocate extra space for another array, you must do this by modifying the input arrayin-placewith O(1) extra memory. You may assume all the characters consist ofprintable ascii char...

The string is basically a sequence of characters. In Java, a string is an object, and there are a number of operations we can perform on the string. As the name suggests, Reversing a string is nothing but flipping the given string — that is, the last letter becomes the first, the se...
