To implement grid-based collision detection in Snake Game, you will need to divide the game area into a grid of cells and track the positions of game elements within these cells. Here's a step-by-step guide on how to implement grid-based collision detection in detail:

Step 1: Set Up the Game Grid

1. Define the size of the game area and the dimensions of each grid cell.
2. Create a two-dimensional array to represent the grid. Each cell in the array will store information about the game elements present in that grid cell.

Step 2: Update Game Elements in the Grid

1. Update the grid with the positions of game elements (snake's head, body segments, food items, walls).
2. Determine which grid cells each game element occupies based on its position in the game area.

Step 3: Detect CollisionsCollision with Snake's Body:

1. Check the grid cell occupied by the snake's head against the grid cells occupied by its body segments.
2. If the snake's head overlaps with any of its body segments in the grid, trigger a collision.
