2589. Minimum Time to Complete All Tasks
Leetcode Solutions
Greedy Approach with Time Slot Tracking
Sort the tasks based on their end times.
Initialize an array used to keep track of used time slots, initially filled with zeros.
Initialize a variable totalTime to keep track of the total time the computer is on.
Iterate over each task in the sorted list.
a. For each task, calculate the number of time slots already used within the task's time range.
b. Calculate the remaining time slots needed to complete the task.
c. Starting from the task's end time and moving backwards, fill the remaining time slots with the task's duration.
d. Update the used array and totalTime accordingly.
Return the totalTime as the minimum time the computer needs to be on.
