Find words that can be formed by characters

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 cntnow the task is to arrange k characters out of cnt characters i.

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.

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 the given array. To solve this problem, we have to compare the frequency of each character in the word with the frequency of that character in the string S. Currently you have JavaScript disabled.

This problem can be solved in following steps :- Create the character array from the input String S. Create an integer array count array of size 26 Total number of characters in the English language , This array will be used to store the frequency of each character in the S string. Increase the count for the calculated index by 1. Traverse the array of words and for each word, repeat steps 1, 2 and 3. If the frequency of any character in the word is greater than the frequency of that character in S string, then that word is not a good word. Add and return the length of all good words.

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.

Given a dictionary, a method to do lookup in dictionary and a M x N board where every cell has one character. Find all possible words that can be formed by a sequence of adjacent characters. Note that we can move to any of 8 adjacent characters, but a word should not have multiple instances of same cell. The idea is to consider every character as a starting character and find all words starting with it. All words starting from a character can be found using Depth First Traversal. We do depth-first traversal starting from every cell. We keep track of visited cells to make sure that a cell is considered only once in a word.
