Leetcode Problem 2187. Minimum Time to Complete Trips

2187. Minimum Time to Complete Trips

Leetcode Solutions

Key approach of the solution: Binary Search

  1. Initialize the search space with left = 1 and right = max(time) * totalTrips.
  2. While left < right, perform the following steps: a. Calculate the middle value mid = (left + right) / 2. b. Initialize a variable trips to store the total number of trips that can be completed in mid time. c. Iterate over each bus time in the time array and add mid / time[i] to trips. d. If trips is greater than or equal to totalTrips, set right = mid as the new upper boundary. e. Otherwise, set left = mid + 1 as the new lower boundary.
  3. Return left as the minimum time required to complete at least totalTrips trips.
