Challenge of the day #15 - **Count** Number of **Pairs** With Absolute **Difference K**. Close. Vote. Posted by 7 minutes ago. Challenge of the day #15 - **Count** Number of **Pairs** With. Here a **k**-diff **pair** is defined as an integer **pair** (i, j), where i and j are both numbers in the array and their absolute **difference** is **k**. Example 1: Input: [3, 1, 4, 1, 5], **k** = 2 Output: 2 Explanation: There are two 2-diff **pairs** in the array, (1, 3) and (3, 5). Although we have two 1s in the input, we should only return the number of unique **pairs**.. Answer is 10. When n == 2, _ _ first digit has 9 choices [1, ..., 9], second one has 9 choices excluding the already chosen one. So totally 9 * 9 = 81. answer should be 10 + 81 = 91 When n == 3, _ _ _ total choice is 9 * 9 * 8 = 684. answer is 10 + 81 + 648 = 739 When n == 4, _ _ _ _ total choice is 9 * 9 * 8 * 7..
