LeetCode ProblemMinimum Number of Work Sessions to Finish the Tasks
There are n tasks assigned to you. The task times are represented as an integer array tasks of length n, where the ith task takes tasks[i] hours to finish. A work session is when you work for at most sessionTime consecutive hours and then take a break. You should finish the given tasks in a way that satisfies the following conditions: Given tasks and sessionTime, return the minimum number of work sessions needed to finish all the tasks following the conditions above. The tests are generated such that sessionTime is greater than or equal to the maximum element in tasks[i].
