Solution: Exclusive Time of Functions
Explore how to calculate the exclusive execution time of multiple functions running on a single-threaded CPU using a stack. Understand how to parse execution logs and apply stack operations to properly allocate running times, including handling nested and recursive functions efficiently. This lesson equips you to implement this solution with optimal time and space complexity.
We'll cover the following...
Statement
We are given an integer number, n, representing the number of functions running in a single-threaded CPU, and an execution log, which is essentially a list of strings. Each string has the format {function id}:{"start" | "end"}:{timestamp}, indicating that the function with function id either started or stopped execution at the time identified by the timestamp value. Each function has a unique ID between and ...
