Binary Search on Time

  1. Convert the ranks array to a long array to prevent integer overflow.
  2. Sort the ranks array.
  3. Initialize the search space with si (start index) as 0 and ei (end index) as a large number (e.g., Long.MAX_VALUE).
  4. Perform binary search: a. Calculate mid as the average of si and ei. b. Use the helper function to check if it is possible to repair all cars in mid time. c. If possible, update the result time and move ei to mid - 1. d. If not possible, move si to mid + 1.
  5. Continue the binary search until si is greater than ei.
  6. Return the minimum time found.
