This is the 2nd Video of our "Leetcode Easy" Playlist.
In this video we will try to solve an easy string problem - Find Words That Can Be Formed by Characters (Leetcode -1160).
I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY.
We will do live coding after explanation and see if we are able to pass all the test cases.
Also, please note that my Github solution link below contains both C++ as well as JAVA code.

Approach Summary :
The solution counts the total length of words that can be formed using characters from a given set. The countCharacters method takes an array of words and a string of characters as input. It iterates through each character in the input string to count the occurrences of each character. Then, for each word in the array, it counts the occurrences of each character in the word and compares it with the counts from the input string. If there are enough characters in the input string to form the word, the length of the word is added to the result. The final result is the sum of the lengths of all valid words. The code includes a main method demonstrating the usage of the countCharacters method with a sample input.
