Trimming Binary Search Trees Problem: Given the root of a BST along with minimum boundary minBound and maximum boundary maxBound, trim the tree so that all remaining node values fall within [minBound, maxBound]. The trimming operation should preserve the relative structure of retained elements. Retu...
Recursive Implementation of Combinatorial Enumeration Given two integers n and m, generate all combinations of m distinct integers from the set {1, 2, ..., n} in lexicographical order. #include <iostream> #include <vector> using namespace std; vector<vector<int>> results; vec...
1. Verifying Identical Binary Trees Given two binary trees, determine if they are structurally identical with matching node values at every position. Empty trees are considered identical. Analysis: The solution requires recursive comparison of corresponding nodes. When both nodes are null, they matc...
Given the root nodes p and q of two binary trees, implement a function to verify if they are structurally identical and contain identical node values. Example: Input: p = [1,2,3], q = [1,2,3] Output: true Approach Two trees are considered identical only when their structures match completely and eve...
