Objectives Practice implementing and using a Queue data structure. Practice using Stack data structure Practice using Set, HashSet data structure Gain an understanding of algorithms used for efficient implementation. Instructions Your program will accept starting and ending words from the input file called "input.txt". Then, you read the dictionary file (can be downloaded from Google Drive) and store it in a HashSet Finally, you build a word ladder between starting and ending words There are several ways to solve this problem. One simple method involves using stacks and queues. The algorithm (that you must implement) works as it follows 1) Get the starting word and search through the dictionary o Find all words that are one letter different. o Create stacks for each of these words, containing the starting word (pushed first) and the word that is one letter different.
