Example 1: Input: s = "anagram", t = "nagaram" Output: true Example 2: Input: s = "rat", t = "car" Output: false Solution : class Solution ( object ): def isAnagram ( self , s , t ): """ :type s: str :type t: str :rtype: bool """ if len (s)!= len (t): return False countS, countT= {},{} for i in range ( len (s)): countS[s[i]]= 1 + countS.get(s[i], 0 ) countT[t[i]]= 1 + countT.get(t[i], 0 ) return countS == countT T...
