Consecutive Author Constraint

Question

Given an array of author identifiers `authors` where each element represents the author of a chapter, determine the maximum length of a subsequence where no two adjacent elements have the same author identifier and the first and last elements are distinct.

To optimally solve the Consecutive Author Constraint problem involving Strings, it is important to analyze constraints. Time Complexity: O(n), Space Complexity: O(n). The optimal approach uses dynamic programming to build up a solution by maintaining two arrays that track the longest subsequences with a different author for the last two chapters. This approach reduces the time complexity to linear.
