Solution: Combinations
Explore how to implement a backtracking algorithm that generates all possible combinations of k numbers from 1 to n. Understand pruning techniques to avoid unnecessary computations and ensure efficient recursion. This lesson helps you grasp core principles of backtracking applied to combination problems commonly encountered in coding interviews.

Statement
You are given two integers, n and k. Your task is to return all possible combinations of k numbers chosen from the range [1, n].
The result can be returned in any order.
Note: Combinations are unordered, i.e., [1, 2] and [2, 1] are considered the same combination.
Constraints:
n...
