2849. Determine if a Cell Is Reachable at a Given Time

Leetcode Solutions

Mathematical Approach to Determine Reachability in a Grid

  1. Calculate the absolute differences in x and y coordinates between the start and end points to determine the minimum number of steps required.
  2. If the start and end points are the same, check if t is not equal to 1. If t is 1, return False; otherwise, return True.
  3. Calculate the minimum time required to reach the destination by taking the maximum of the differences in x and y coordinates.
  4. If t is greater than or equal to the minimum time, return True; otherwise, return False.
