Answer from cs61c-es (Meng Chang Bruce Lin 16075852) for Question 5 I have read the PH notes and was a little concerned on the malloc issues. I am a bit confused on the buddy system, the mark and sweep method and some other techniques that was described. My main question is that as a programmer or someone who is learning malloc, how does these techniques help us to improve our codes. I would like to see some demonstration on how one might choose different scheme to implement memory allocations.
