- * mm-naive.c - The fastest, least memory-efficient malloc package.
- * 
- * In this naive approach, a block is allocated by simply incrementing
- * the brk pointer.  A block is pure payload. There are no headers or
- * footers.  Blocks are never coalesced or reused. Realloc is
- * implemented directly using mm_malloc and mm_free.
- *
- * NOTE TO STUDENTS: Replace this header comment with your own header
- * comment that gives a high level description of your solution.
