967\. Numbers With Same Consecutive Differences

Medium

Return all **non-negative** integers of length `n` such that the absolute difference between every two consecutive digits is `k`.

Note that **every** number in the answer **must not** have leading zeros. For example, `01` has one leading zero and is invalid.

You may return the answer in **any order**.

**Example 1:**

**Input:** n = 3, k = 7

**Output:** [181,292,707,818,929]

**Explanation:** Note that 070 is not a valid number, because it has leading zeroes.

**Example 2:**

**Input:** n = 2, k = 1

**Output:** [10,12,21,23,32,34,43,45,54,56,65,67,76,78,87,89,98]

**Constraints:**

*   `2 <= n <= 9`
*   `0 <= k <= 9`
