Determine the block sizes and header values:

Original questions are like this picture.

What if requests are malloc(4), malloc(7), malloc(19), and malloc(22), what are the block sizes(decimal bytes) and block headers(hex)?

Please answer them!

Determine the block sizes and header values that would result from the following sequence of malloc requests. Assumptions: (1) The allocator maintains doubleword alignment, and uses an implicit free list with the block format from Figure 9.35. (2) Block sizes are rounded up to the nearest multiple of 8 bytes Block size (decimal bytes) Block header (hex) Request malloc(3) malloc (11) malloc(20) malloc (21) Figure 9.35 Format of a simple heap malloc relums a S1 Header 3 2 1 0 aAWocated poal}a- block povnler to he bewing of the payWoad ginning _+ _ Block size The block size cdes Payload (allocaled block only)the aden any padding Padding (optional) Determine the block sizes and header values that would result from the following sequence of malloc requests.
