What's the complexity of this decision tree solution? Well, in the worst case, we're enumerating every possibility of in and out.
决策树解决方法的复杂度是多少?,在最糟的例子中得列举,所有可能的输入和输出。
Right? If that was the case in that code, then my complexity is no longer log, because I need linear access for each time I've got to go to the list, and it's going to Lisp be much worse than that.
这里的复杂度不再是对数的了,因为每次在列表中,查找需要线性访问,可能还要糟糕,其实,有些编程语言,如。
In the linear case, meaning in the unsorted case what's the complexity of this? k times n, right? Order n to do the search, and I've got to do it k times, so this would be k times n.
复杂度是多少?k的n次方,对吧?,在序列n中做搜索,要做k次,所以是k的n次方次,如果先排序后搜索。
