// CODE_RUNNER: Arrays Homework

// Exercise 1 - Array Basics

// Create an array with 5 items
let favorites = ["Strawberry", "Apple", "Watermelon", "Grape", "Orange"];

// Print the entire array
console.log("Full array:", favorites);

// Print the first element (index 0)
console.log("First item:", favorites[0]);

// Print the last element
console.log("Last item:", favorites[favorites.length - 1]);

// Print the length
console.log("Total number of items:", favorites.length);







// Exercise 2 - Arrays Manipulation

// Start with the shopping list
let shoppingList = ["milk", "eggs", "bread", "cheese"];

// Print the original array
console.log("Original shopping list:", shoppingList);

// Change the second item to “butter”
shoppingList[1] = "butter";

// Add “yogurt” to the end using push()
shoppingList.push("yogurt");

// Remove “bread” from the array
let breadIndex = shoppingList.indexOf("bread");
if (breadIndex !== -1) {
  shoppingList.splice(breadIndex, 1);
}

// Print the final array
console.log("Final shopping list:", shoppingList);






// Exercise 3 - Loop Through an Array

// Create the numbers array
let numbers = [10, 25, 30, 15, 20];

// Print each number with a message
for (let i = 0; i < numbers.length; i++) {
  console.log("Number:", numbers[i]);
}

// Print each number multiplied by 2
for (let i = 0; i < numbers.length; i++) {
  console.log("Multiplied by 2:", numbers[i] * 2);
}

// Calculate and print the sum
let sum = 0;
for (let i = 0; i < numbers.length; i++) {
  sum += numbers[i];
}

console.log("Sum of all numbers:", sum);
