The search() method should return the IntNode whose data value matches a given key, and null if the key is not found. The search() method should also set the position of each IntNode searched in the IntList, starting with 1. Ex: If the input is: 12 23 59 37 923 2 -1 12 the output is: 12 found in list at position 1.

- Python write a program in python that plays the game of Hangman. When the user plays Hangman, the computer first selects a secret word at random from a list built into the program. The program then prints out a row of dashes asks the user to guess a letter. If the user guesses a letter that is in the word, the word is redisplayed with all instances of that letter shown in the correct positions, along with any letters correctly guessed on previous turns. If the letter does not appear in the word, the user is charged with an incorrect guess. The user keeps guessing letters until either: * the user has correctly guessed all the letters in the word or * the user has made eight incorrect guesses. one for each letter in the secret word and Hangman comes from the fact that incorrect guesses are recorded by drawing an evolving picture of the user being hanged at a scaffold. For each incorrect guess, a new part of a stick-figure body the head, then the body, then each arm, each leg, and finally…Array List: Write a program that reads in words and prints them out in reverse order.
