题目要求 Given two strings s and t , write a function to determine if t is an anagram of s. 题目分析及思路 给出两个字符串s和t,要求判断t是否是s的一个anagram,即由相同的字母且不同的字母顺序组成.可以使用collections.Counter统计每个字符串中不同字母的的个数,若两个字符串中的字母种类和个数都相等,则可判定t是s的一个anagram. python代码 class Solution: de…

Given two strings s and t , write a function to determine if t is an anagram of s. Example 1: Input: s = "anagram", t = "nagaram" Output: true Example 2: Input: s = "rat", t = "car" Output: false 题意: 验证变位词 何谓anagram…

[字符串与数组] Q:Write a method to decide if two strings are anagrams or not 题目:写一个算法来判断两个字符串是否为换位字符串.(换位字符串是指组成字符串的字符相同,但位置不同) 解答: 方法一:假设为ascii2码字符串,那么可以分配两个256大小的int数组,每个数组用于统计一个字符串各个字符出现的次数,最后,比较这两个int数组,看是否每个元素都相同.时间复杂度为O(n). int anagrams1(char* str1,c…
