write a Word ladder VB$.$NET prograem

Description

A word ladder is a game$/$puzzle where the user is given a word and has to make a new word by changing exactly one letter, repeating this process to make more words. Some versions of the game have a starting word, a target word, and a number of tries $($e$.$g$.$ CAT to DOG in three changes could be CAT $->$ COT$->$ DOT $->$ DOG$).$ This version will give the player a random word, selected from a list, and see how long a chain of words they can get without repeating.

Example output:

Make a new word by changing only one letter:

The current word is BIRD

BARD

The current word is BARD

HARD

The current word is HARD

HARP

The current word is HARP

CART

You changed two letters, game over.

Your score is $3$

Part $1$: Setup

Create a list$/$array of $4-$letter words $($loaded from a file or copied from the list in this document$)$ and output a random word from the list as the current word.

Hint: $[$save the file in U:$]$ words $=$ IO$.$File.ReadAllLines$("$U:$/$words$4$letters.txt$").$ToList$()$

Part $2$: New word

Have the user enter a new word. If the word is not exactly four letters long or the word differs by more than one letter, the game ends, otherwise the game continues and the user's score increases by one. If the game has not ended, the current word is set to the user's new word ready for the next turn.

Hint: check pairs of letters in the previous and new word and count how many letters ae the same$/$different $($if oldword$($i$)=$ newword$($i$)$ then...$)$ Repetition & valid words

Have the game end if the user gives a word that is not in the list or they repeat a word they have already used. At the end of the game, tell the user their score.
