Solution: Combinations
Explore the backtracking approach to solve combinatorial problems by generating all unique combinations of k numbers from a range of 1 to n. Learn the recursive method that builds combinations step-by-step, uses pruning to optimize, and manages time and space complexity effectively.

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...
