Solution: Koko Eating Bananas

Explore how to apply modified binary search techniques to determine the minimum constant eating speed that allows Koko to finish all bananas within a limited time. Understand the problem's monotonic behavior and efficiently compute the solution while managing time and space complexity. This lesson develops your problem-solving skills for similar coding interviews.

We'll cover the following...

Statement

Koko has nn piles of bananas in front of her, where the ithi^{th} pile has piles[i] bananas. The guards have left and will return in h hours, and Koko must finish all the bananas before they come back.

Before eating, Koko chooses an integer as an eating speed kk ...
