For different data structures such as linked lists, arrays (sorted/unsorted, trees etc. of size n, what is the worst-case time-complexity of finding the n/2 smallest values in each of them? Is it the same as the complexity for Find operations?
Edit: So, what s the complexity for these data structures? Unsorted Linked list, unsorted array, splay trees and hash tables?
Not necessarily. For instance, for a sorted array you can find the n/2 smallest values in constant time.
它完全取决于数据结构,它是否是分类的。
如果你认为树木是平衡的,那么发现最小的数值是...... “所有价值观都与根基的“ft”。
You cannot generalize it quite as much, it depends fully on the data structure.
如果不具体说明算法,或至少说明数据结构,就不可能具体说明问题的复杂性。 有一些数据结构是绝对的夜班,没有使用更适合的中间储存结构。 举例来说,紧缩比阵列要困难得多,因为你不能随意抽取分子。
