Longest Distinct Circular Subsequence Solution
Problem Statement
Given a circular array of integers `elements`, determine the length of the longest contiguous subsequence that contains no duplicate elements.
Constraints
- The length of the input array is between 1 and 1000.
- Each element in the array is an integer between 1 and 10000.
Time: O(n) Space: O(min(n, m))
The optimized approach utilizes a sliding window technique in conjunction with a hash set to efficiently track unique elements within the current window, allowing for a significant reduction in time complexity.
