*"2657. Find the Prefix Common Array of Two Arrays"* is a medium-level problem and the LeetCode daily challenge (POTD) for 14 January 2024. The solution, written in Java, is explained with a dry-run on a blackboard, making it accessible to viewers with diverse programming backgrounds by focusing on the logic rather than language-specific details.

*Intuition:*
To determine the prefix common array of two arrays, you can utilize two sets to track elements encountered in both arrays up to each index
𝑖. As you iterate, add elements from both arrays into their respective sets and check for intersections to identify common elements. This approach efficiently captures the shared elements at each prefix, enabling you to build the prefix common array step by step.
