Leetcode Problem 1665. Minimum Initial Energy to Finish Tasks

1665. Minimum Initial Energy to Finish Tasks

Leetcode Solutions

Greedy Approach with Sorting

  1. Sort the tasks based on the saved energy, which is minimum - actual, in ascending order.
  2. Initialize initial_energy and current_energy to 0.
  3. Iterate through the sorted tasks: a. If current_energy is less than the minimum energy required for the current task, calculate the difference and add it to initial_energy. b. Update current_energy to be the maximum of current_energy and minimum energy for the current task, then subtract the actual energy spent on the task.
  4. Return initial_energy as the minimum initial energy required to finish all tasks.
