In a binary tree, a lonely node is a node that is the only child of its parent node. The root of the tree is not lonely because it …
Merge k sorted linked lists and return it as one sorted list. Analyze and describe its complexity. Example: Input: Output: 1->1->2->3->4->4->5->6 There are many algorithms that we can use …
Given a binary tree, return the sum of values of its deepest leaves. Example 1: Input: root = Output: 15 Constraints: The number of nodes in the tree is …
Given a list of intervals, remove all intervals that are covered by another interval in the list. Interval ,,] Output: 2 Explanation: Interval is covered by , therefore it …
nth_element is a partial sorting algorithm which can be invoked by including the header algorithm. It has following two forms: void nth_element(_RanIt _First, _RanIt _Nth, _RanIt _Last); void nth_element(_RanIt …
