Input: s = "leetcode", t = "practice" Output: 5 Explanation: Replace 'p', 'r', 'a', 'i' and 'c' from t with proper characters to make t anagram of s. Example 3: Input: s = "anagram", t = "mangaar" Output: 0 Explanation: "anagram" and "mangaar" are anagrams. Description Given a string s and a non-empty string p, find all the start indices of p's anagrams in s. Strings consists of lowercase English letters only and the length of both strings s and p will not be larger than 20,100. Given a string s and a non-empty string p, find all the start indices of p ‘s anagrams in s. Strings consists of lowercase English letters only and the length of both strings s and p will not be larger than 20,100.

To take advantage of alphabetic number only has constant of size \$26\$, go through the string once, one char a time, to record the number of occurrence, like a counting sort. The order of output does not matter. e.g. Note that in Java, toCharArray() makes a copy of the string so it costs O (n) O(n) O (n) extra space, but we ignore this for complexity analysis because: It is a language dependent detail. Note: All inputs will be in lower-case. If you do that, then the implementation of the other method becomes simply: The code violates many good practices and common conventions: Jianmin commented on my answer to a similar question here: Grouping anagrams and it got me thinking about the problem, and also reading this solution. 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 Note: You may assume the string contains only lowercase alphabets.
