回答: What else can you do? if the problem is inherently recursive, Like qsort? 由 steven 于 2008-02-08, 02:06:12:
1. recursion should be avoided for trees. 2. "层数越多就越慢" is not necessarily true for trees, because more nodes on each layer will slow it down also.
3. I'll use recursion for a problem that is inherently recursive. Actually I won't have much chance to encounter a problem that requires a data structure more complicated than an array.
