Exclusive Time of Functions

Explore how to calculate the exclusive time of functions running on a single-threaded CPU by interpreting start and end logs. Understand how stacks manage function execution and interruptions, and practice implementing solutions to track precise running times for each function based on log timestamps.

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 ...
