Iteration Homework

Homework Assignment: for Loop Challenge

Task: Create a program that does the following:

Initialize an array with the names of five of your favorite movies. Use a for loop to iterate through the array and print each movie name to the console. After printing all movie names, print a message indicating how many movies you listed.

Homework

Create a 3 by 3, 2D list that represents a tictactoe board. Use “X” for X, “O” for O, and None for empty tiles.

Ex. board = [[“X”,”None”,”O”],
       [“X”,”O”,”None”],
       [“O”,”None”,”X”]]

Iterate over the board and identify whether it is player X’s or player O’s turn.

Hint: count the number of moves(non-None). (X goes first)

Optional: use console.error() to report an error if the board is illegal (ex. 7 “X”s and 2 “O”s)

%%js
let board = [
  ["X", null, "O"],
  ["X", "O", null],
  ["O", null, "X"]
];

// Count the moves
let countX = 0;
let countO = 0;

for (let row of board) {
  for (let cell of row) {
    if (cell === "X") countX++;
    if (cell === "O") countO++;
  }
}

// Determine whose turn it is
if (countX === countO) {
  console.log("It's player X's turn.");
} else if (countX === countO + 1) {
  console.log("It's player O's turn.");
} else {
  console.error("Illegal board: count of Xs and Os is not valid.");
}

H.W application of While Loops.

Create the Outer Loop:

Use a while loop that runs while outerFactor is less than or equal to 10. Initialize the Inner Loop Variable:

Inside the outer loop, create another variable called innerFactor and set it to 1. Create the Inner Loop:

Inside the outer loop, use another while loop that runs while innerFactor is less than or equal to 10. Calculate the Product:

Inside the inner loop, calculate the product of outerFactor and innerFactor. Print the Product:

Print the product using console.log(), formatting the output neatly. Increment the Inner Loop Variable:

After printing the product, increment innerFactor by 1. Move to the Next Line:

After the inner loop finishes, print a new line to separate rows. Increment the Outer Loop Variable:

Increment outerFactor by 1 to move to the next row in the table.
