Since there is such an important conclusion, we can safely drop the first k/2 element in A, which are definitaly smaller than k-th element in the union of A and B. This is also true for the A[k/2-1] > B[k/2-1]
另外一个函数签名一样的: set_union 这个会把重复元素除掉,需要注意。 + View Code
21. Merge Two Sorted Lists # 题目 # Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. Example: Input: 1->2->4, 1->3->4 Output: 1->1->2->3->4->4 题目大意 # 合

很多人连Segment Tree,BIT,Trie,Union Find这种数据结构都不懂,遇见就刷,自己想,怎么可能想的出来? 所以刷题最重要的,第一步,就是了解所有的数据结构,做题方法,基础算法。从基础数据结构HashMap,HashSet,到TreeSet,TreeMap,Deque,LinkedHashMap;到各种对刷题来说的基础算法,各种排序算法,DFS,BFS,Sliding Window...
Each union and find operation is nearly constant time due to path compression and union by rank, making the amortized time complexity very efficient. Space Complexity: O(V), as we need to maintain the parent and rank arrays. The space used is proportional to the number of vertices in the ...
