Question: Some word games require the player to find words that can be formed using the letters of another word. For example, given the word SWIMMING, other words that can be formed using the letters include SWIM, WIN, WING, SING, MIMING, etc. Write a program that lets the user enter a word and then output all the words contained in the file words.txt that can be formed from the letters of the entered word. One algorithm to do this is to compare the letter histograms for each word. Create an array that counts up the number of each letter in the entered word (e.g., one S, one W, two I, two M, etc.) and then creates a similar array for the current word read from the file. The two arrays can be compared to see if the word from the file could be created out of the letters from the entered word.
