Started with pen-and-paper chaos, ended with a 2D array making sense.
Rows, columns, nested loops, brain hurt a little, but it clicked.
Learning JavaScript isn’t about writing code first,
its about learning how to think.

✅ GFG POTD: 2D Difference Array
🧠 Used a 2D prefix-diff matrix to apply range updates in constant time, followed by cumulative row & col sums to build the final matrix.
Smart and efficient!
