Solution: Combinations
Explore how to implement a backtracking algorithm to generate all unique combinations of k numbers from a range of 1 to n. Understand the recursion, pruning strategies, and the step-by-step approach to efficiently build and backtrack combinations without repetition. This lesson helps develop skills to solve combinatorial problems methodically.

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:
