Solution: Combinations
Explore how to implement backtracking to generate all possible combinations of k numbers chosen from a range of 1 to n. This lesson explains the recursive process, pruning strategies to optimize exploration, and how the algorithm builds each combination step-by-step. You will understand the time and space complexity and be able to apply this pattern to similar coding challenges.

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...
