2d Arrays: 8.1.5 Manipulating
Imagine you are at grid[r][c] .
Always ensure your indices stay between 0 and length - 1 . If you are checking a "neighbor" at r + 1 , your loop should only run until matrix.length - 2 . 4. Advanced Manipulation: The Enhanced For-Loop 8.1.5 manipulating 2d arrays
A classic 2D array problem involves checking "neighbors" (up, down, left, right) of a specific cell. This is common in game development (e.g., Minesweeper or Conway's Game of Life). Imagine you are at grid[r][c]
You use an enhanced for-loop to replace a primitive value (like an int ) or change the structure of the array. 8.1.5 manipulating 2d arrays
