// Example 2: Multiply by 2 // array[r][c] = array[r][c] * 2; Codehs 8.1.5 Manipulating 2d Arrays

Logic:

Treat each row as a single unit. Instead of swapping individual elements, we can swap the references (in Java) or loop through columns (in languages without pointer arrays). Manipulating 2D Arrays in CodeHS: A Comprehensive Guide
