1497. Check If Array Pairs Are Divisible by k | Leetcode Daily (POTD) 1 Oct 2024 | Java | Hindi

"1497. Check If Array Pairs Are Divisible by k" is a medium-level problem and the daily challenge (POTD) for 1 October 2024 on LeetCode. The solution presented in the video is coded in Java, but the approach is explained using a dry-run on a blackboard. This method makes the video accessible and beneficial for individuals with different programming backgrounds, as it focuses on the underlying logic rather than language-specific details.

Intuition:
To form valid pairs, if one number in the pair has a remainder of `x` when divided by `k`, the other number must have a remainder of `k - x`. This ensures that the sum of both numbers is divisible by `k`. Special care is needed for pairs where the remainder is zero.
