Project 9: The digital root of a positive integer is found by summing the digits of the integer. If the result value is a single digit then that digit is the digital root. If the resulting value contains two or me digits, those digits are summed and the process is repeated. This is continued as long as necessary obtain a single digit. For example, consider the positive integer 24. Adding the 2 and the 4 yield: value of 6. Since 6 is a single digit, 6 is the digital root of 24. Now consider the positive integer Adding the 3 and the 9 yields 12. Since 12 is not a single digit, the process must be repeated. Add the 1 and the 2 yields 3, a single digit and also the digital root of 39. File: Input The input file will contain a list of positive integers, one per line. The end of the input will indicated by an integer value of zero. Output File: For each integer in the input, output its digital root on a separate line of the output.

Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Project 9:
The digital root of a positive integer is found by summing the digits of the integer. If the resultin
value is a single digit then that digit is the digital root. If the resulting value contains two or mom
digits, those digits are summed and the process is repeated. This is continued as long as necessary t
obtain a single digit. For example, consider the positive integer 24. Adding the 2 and the 4 yields
value of 6. Since 6 is a single digit, 6 is the digital root of 24. Now consider the positive integer 39
Adding the 3 and the 9 yields 12. Since 12 is not a single digit, the process must be repeated. Addins
the 1 and the 2 yields 3, a single digit and also the digital root of 39.
Input File:
The input file will contain a list of positive integers, one per line. The end of the input will be
indicated by an integer value of zero.

Assignment 5B: Keeping Score. Now that we know about arrays, we can keep track of when events occur during our program. To prove this, let's create a game of Rock-Paper-Scissors. For those not familiar with this game, the basic premise is that each player says "Rock-Paper- Scissors!" and then makes their hand into the shape of one of the three objects. Winners are determined based on the following rules: Rock beats Scissors Scissors beats Paper Paper beats Rock At the start of the program, it will ask the player how many rounds of Rock-Paper- Scissors they want to play. After this, the game will loop for that many number of times. Each loop, it will ask the player what item they want to use – Rock, Paper, or Scissors. The computer will randomly generate its own item, and a winner will be determined. The game will then save the result as an element of an array, and the next round will begin. Once all the rounds have been played, the program will say "Game Over" and display a list of who…

Python tic tac toe. Tic tac toe is a very popular game. Only two players can play at a time. Game Rules Traditionally the first player plays with "X". So you can decide who wants to go with "X" and who wants to go with "O". Only one player can play at a time. If any of the players have filled a square then the other player and the same player cannot override that square. There are only two conditions that may match will be a draw or may win. The player that succeeds in placing three respective marks (X or O) in a horizontal, vertical, or diagonal row wins the game. Winning condition Whoever places three respective marks (X or O) horizontally, vertically, or diagonally will be the winner. Submit your code and screenshots of your code in action. Hints : Have a function that draws the board Have a function that checks position if empty or not Have a function that checks player or won or not expected output:
