Enamel is actually a fused glass surface. Le Creuset and Chantal are two
quality enamel brands. With proper care, a fine enamel pot lasts a lifetime,
whereas inexpensive enamel cookware from variety stores has such a thin
enamel layer that it chips easily and is not worth its purchase price. Once
chipped, discard enamel kitchenware or enamel fragments will find their way
into your food and the underlying metal will react with food. If i... 阅读全帖 |

发帖数: 445 | 14 我的感觉是：
1. circular link list不需要额外的data structure,直接在block的前面留两个byte
or word表示状态，即可。而且是直接访问，不想tree，那样间接访问。
2. 当需要merge/de-fragmentation时，link list就很方便了直接merge毫无压力,O(1)
时间。但是tree就不一样了，tree要满足bst的性质，旋转子树是在所难免的。
当然通常的search for a proper size block,link list需要O(N)时间，而tree则只需
要O(logn).但是实际系统应该是用一个额外的list来链接free block的。
