Challenge 2: MineSweeper Game

Objective

Develop the mineSweeper function that evaluates a player's move in a grid-based minefield game. The function should analyze the grid position based on provided coordinates and determine if the player has landed on a safe spot or a mine.

Function

function mineSweeper(grid, x, y)

Parameters

  • grid: An array of arrays representing the game grid.
  • x: The x-coordinate (horizontal position) in the grid.
  • y: The y-coordinate (vertical position) in the grid.

Grid Structure

The grid consists of a 3x3 array of strings, where:

  • "🟥" represents a mine.
  • "🟦" represents a safe spot.

Example:

[ 
  ["🟥", "🟦", "🟥"],
  ["🟦", "🟥", "🟥"],
  ["🟥", "🟦", "🟦"]
]

The grid is interpreted with x and y coordinates ranging from 1 to 3.

  • x = 1 and y = 1 represents the top-left square.
  • x = 3 and y = 1 represents the top-right square.
  • x = 3 and y = 3 represents the bottom-right square.

Requirements

  1. If the coordinates land on a red square ("🟥"), return "🟥 💀".
  2. If the coordinates land on a blue square ("🟦"), return "🟦 🥳".
  3. If x or y is less than 1 or greater than 3, return "invalid coordinates".

Examples

Example 1: Landing on a Mine

let grid = [["🟥", "🟦", "🟥"], ["🟦", "🟥", "🟥"], ["🟥", "🟦", "🟦"]];
let result = mineSweeper(grid, 1, 1);
console.log(result);

Expected Output

"🟥 💀"

Example 2: Landing on a Safe Spot

let grid = [["🟥", "🟦", "🟥"], ["🟦", "🟥", "🟥"], ["🟥", "🟦", "🟦"]];
let result = mineSweeper(grid, 2, 3);
console.log(result);

Expected Output

"🟦 🥳"

Example 3: Invalid Coordinates

let grid = [["🟥", "🟦", "🟥"], ["🟦", "🟥", "🟥"], ["🟥", "🟦", "🟦"]];
let result = mineSweeper(grid, 4, 1);
console.log(result);

Expected Output

"invalid coordinates"
