Maximize resource cost control

topic description

The company's innovation laboratory is studying how to minimize resource costs and maximize resource utilization. Please design an algorithm to help them solve a task mix problem: there are taskNum tasks, and each task has a start time (startTime) and an end time (endTime) ), parallelism (parallelism) three attributes, parallelism refers to the number of servers that will be occupied when the task is running, a server can be used by any task at each moment but is occupied by one task at most, and the task will be released immediately after running ( The end time is not occupied). The task mixing problem refers to given a batch of tasks, let this batch of tasks be assigned by
