Task 3 / 47
MallocLab
The CSAPP-style Malloc Lab: implement `malloc`/`free`/`realloc` in a constrained region to maximize utilization and throughput on realistic allocation traces. It exercises segregated lists, coalescing, and throughput-oriented heuristics, scored by an mdriver-like harness for correctness and performance.
