Video Summary :
First, build a 2D prefix sum so the sum of any square can be computed in constant time.
Approach 1 : fixes each cell as the top-left corner and keeps expanding the square greedily until the sum crosses the threshold.
Approach 2 : observes that if a square of side k works, smaller squares will also work, so it binary searches on the side length.
Prefix sums are the key that make both approaches efficient by avoiding repeated sum calculations.
