Flood Fill
Explore how to apply the flood fill algorithm using backtracking to update pixel colors in a 2D grid. Understand the step-by-step process starting from a given pixel and spreading to adjacent pixels with the same color. This lesson helps you implement a common pattern useful in coding interviews involving grid traversal and recursive problem solving.
