Last Moment Before All Ants Fall Out of a Plank

To find the time when the last ant falls off the plank, we calculate the maximum time taken by ants moving left and right. For ants moving left, we consider their positions and for ants moving right, we calculate the time to reach the right end of the plank. The time to fall off the plank for each ant is independent of collisions. The maximum time among all ants will be the time when the last ant falls off the plank. This solution efficiently handles multiple ants with time complexity O(m).
