Find words that can be formed by characters

You have given an array of words and a string S. A word is good if it can be formed by using characters from string S each character can only be used once. Write a program to find out the sum of the length of all good words in hearthpwn given array.

A simple solution is to try all characters one by one. If all characters satisfy this condition, return true. Else return false. An efficient solution is to create a frequency array of length Number of possible characters and initialize it to 0. Skip to content. Change Language. Open In App.

Find words that can be formed by characters

In this problem, we are given two inputs: an array of strings called words and a single string called chars. Our task is to determine which strings in the words array are "good". A "good" string is one that can be completely formed using the characters in chars. Each character in chars may only be used once when forming a word. After identifying all the "good" strings, we must calculate the sum of their lengths and return that sum as the result. The lengths of "cat" and "hat" are 3 and 3, respectively, so the sum is 6. The goal of the problem is to implement a function that can do this calculation for any given words and chars. Count Characters in chars : We first count the frequency of each character in the string chars. This helps us know how many times we can use a particular character while forming words. Iterate Over words : Next, we loop through each string in words and count the frequency of each character in the current string w. Check if a Word Can be Formed: To determine if a word is "good", we compare character frequencies of the current word with those in chars.

Given an integer k and a string str consisting of lowercase English alphabets, the task is to count how many k-character words with or without meaning can be formed from the characters of str when repetition is not allowed. Approach: Count the number of distinct characters in str and store it in cnt , now the task is to arrange k characters out of cnt characters i. Time Complexity: O n , where n is the length of the given string. Auxiliary Space: O 1. Skip to content. Change Language. Open In App.
