Solution: Combinations
Understand how to implement backtracking to find all possible combinations of k numbers from the range 1 to n. This lesson guides you through building each combination recursively, pruning impossible paths to optimize performance and handling the complexity involved.

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...
