 For a task `i`:

+* `tasks[i].cookies` is how many cookies he will get for finishing `task[i]` 
 
 Unfortunately, he sucks at multitasking. Write a **function** which returns the maximum amount of cookies he can get without any tasks overlapping. 
 Your function must have this signature:
 
 ```rust
-pub fn time_manager(tasks: &mut Vec<Task>) -> u32
+pub fn time_manager(tasks: &mut [Task]) -> u32
 ```
