mediumStringsPattern: Mixed
Cyclic Character Sequence Validator Solution
Problem Statement
Given a string `sequence`, determine if it can be rearranged into a cyclic sequence of characters where 'k' follows 'j', and all other characters follow alphabetically.
Constraints
- The input string will only contain lowercase letters.
- The length of the input string will not exceed 500 characters.
Time: O(n) Space: O(n)
A more efficient approach involves using a data structure such as a linked list or a circular buffer to keep track of the characters and their order in the sequence, allowing for a time complexity of O(n). This approach takes advantage of the fact that the sequence has a specific pattern and can be rearranged efficiently.
