二分法只能作用于有序数组(例如排序后的Python的list),但是有序数组较难维护,因为插入需要线性时间;二叉搜索树有些复杂,动态变化着,但是插入和删除效率高了些;字典的效率相比而言就比较好了,插入删除操作的平均时间都是常数的,只不过它还需要计算下hash值才能确定元素的位置。 3.顺序统计量 在算法导论中一组序列中...
I had a problem.An array contained a lot of items, and I wanted to divide it into multiple chunks.I came up with 2 completely different solutions.A) The first was to divide the array in equal chunks, for example chunks of 2 or 3 items B) The second was to create n chunks and ...

As suggested by the name it’s function is just to divide the problem into sub-problem which in turn if are more complex then are again divided into more sub-parts. Basically , if we consider for example binary search ( an example of Divide and Conquer approach ) the given list is ...
The full pseudo-code is given in Algorithm 1. Initially, the set of points is set to be empty at line 1. In each iteration, the algorithm calls theenumerateprocedureFootnote1which returns the next element from a (possibly infinite) list of expressions such that no two expressions in this ...
