https://leetcode.com/problems/search-for-a-range/ Given a sorted array of integers, find the starting and ending position of a given target value. Your algorithm's runtime complexity must be in the order ofO(logn). If the target is not found in the array, return[-1, -1]. For exam...

Simulation Expirment for Proofing the Theoretical Assumption of Time Complexity for Binary Search TreeMuna M. SalihBaghdad University
Structures in an efficient way in Java with references to time and space complexity. These Pre-cooked and well-tested codes help to implement larger hackathon problems in lesser time. DFS, BFS, LCA, LCS, Segment Tree, Sparce Table, All Pair Shortest Path, Binary Search, Matching and many ...
In the worst case, we need to traverse the entire o tree to find the parent, which makes the iterative solution O(n) in space complexity. Again, if the BST is well-balanced, we can do the same in O(log n). When we reach a leaf node, we start polling elements from the parentCan...
Consider the following binary search tree: 5 / \ 2 6 / 1 3 Example 1: Input: [5,2,6,1,3] Output: false Example 2: Input: [5,2,1,3,6] Output: true Follow up: Could you do it using only constant space complexity? 我的答案:TLE了 ...
If changed 100100 to nn, the complexity of the guessing will be at most O(logn)O(logn). Why are you using binary search when seeing the problem? Let's consider the following monotonous function f(x)f(x): And you are querying the middle place, if too small: Otherwise, it's ...
