Chebyshev Distance is a metric used to measure the distance between two points in a grid-based system. It calculates the maximum difference along any coordinate dimension. For example, in a two-dimensional space, the distance is determined by finding the largest difference between the x-coordinates and y-coordinates of the two points. This distance metric is particularly useful in scenarios where movement can occur in any direction, such as in chess, where a king can move one square in any direction. It is also applicable in various fields, including computer science and robotics, for pathfinding and spatial analysis.
