Get Function Execution Time

Problem Overview

• Compute exclusive execution time for n functions on a single-thread CPU using preemptive logs.
• Input: n and logs id:start|end:timestamp; Output: int array of times for IDs 0..n-1, including start and end seconds.
• Logs sorted with non-decreasing timestamps; each start has a matching end; 1≤n≤100, 1≤m≤500.
• Context: task scheduling and profiling in preemptive systems.
• From Capital_one interviews; a coding interview question/problem.
