Given a string array words, find themaximum value of length(word[i]) * length(word[j]) wherethe two words do not share common letters. You may assume that each word willcontain only lower case let

Given an array of numbers nums, in which exactly two elements appear only once and all the other elements appear exactly twice. Find the two elements that appear only once.For example:Given nums

Given an array of n integerswhere n > 1, nums, return an array output suchthat output[i] is equal to the product of all theelements of nums except nums[i].Solve it withoutdivision and in O(n).Fo

Given two strings s and t,write a function to determine if t is an anagram of s.For example,s ="anagram", t = "nagaram", return true.s ="rat", t = "car", return false.Note:You may assume the

You are playing the following Bulls and Cows game with your friend: You write down a number and ask your friend to guess what the number is. Each time your friend makes a guess, you provide a hint that

Given a pattern and a string str, find if str follows the same pattern.Here follow means a full match, such that there is a bijection between a letter in pattern and a non-empty word in str.Examples:

Given an integer array nums, find the sum of the elements between indices i and j (i ≤ j), inclusive.Example: Given nums = [-2, 0, 3, -5, 2, -1]sumRange(0, 2) -> 1 sumRange(2, 5) -> -1 sumRange(0, 5
