Longest Consecutive Sequence (Hard) Given a set of N objects: Union command: replace components containing two objects with their union An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. To solve this problem we will use a frequency array and that will store the count of characters present in the string. In the problem ” Find Words That Can Be Formed by Characters” we are given an array of strings that consists of lower case English alphabets (words) and a string that consists of a set of characters (chars). The idea is to use hashing. Create a frequency array and store the frequency of characters of the chars string. 30 – Substring with Concatenation of All Words You are given a string, s, and a list of words, words, that are all of the same length.
