Exclusive Time of Functions
Understand how to calculate the exclusive time of functions from logs in a single-threaded CPU environment. Learn to use stack-based patterns to track function start and end times, handling preemptions accurately. This lesson helps you master problem-solving techniques essential for coding interviews involving execution logs and time calculations.
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 ...
