For solving the DSA problem around 20 minutes were allotted and the interviewer is also helpful and guiding while I am writing the code and Discussing the approach

Find all valid combinations of k numbers that sum up to n such that the following conditions are true: Only numbers 1 through 9 are used. Each number is used at most once. Return a list of all possible valid combinations. The list must not contain the same combination twice, and the combinations may be returned in any order.

Example 1: Input: k = 3, n = 7. Output: [[1,2,4]]. Explanation: 1 + 2 + 4 = 7. There are no other valid combinations.

Example 2: Input: k = 3, n = 9, Output: [[1,2,6],[1,3,5],[2,3,4]]. Explanation: 1 + 2 + 6 = 9. 1 + 3 + 5 = 9. 2 + 3 + 4 = 9. There are no other valid combinations.
