mediumRecursionPattern: Mixed
Balanced Hyperjump Sequences Solution
Problem Statement
Generate all possible valid combinations of 'J' (hyperjump) and 'S' (hyperslow) sequences of length 10, where every 'J' has a corresponding 'S', and no sequence is a substring of another. Return these combinations as a list of strings.
Examples
Example 1:
Input:5
Output:["JJJSS","JJSSJ","JJSJS","JSJJS","JSSJJ","SSJJJ"]
Explanation: These are the valid combinations where every hyperjump has a corresponding hyperslow, and no combination is a substring of another.
Constraints
- 1 <= n <= 10, where n is the number of pairs of hyperjumps and hyperslows
- The output list should not contain any duplicate combinations
Time: O((2n)! / (n! * n!)) Space: O(2n)
A more efficient approach would be to use recursion to build up valid combinations. This approach would have a time complexity of O((2n)! / (n! * n!)) and would be much more efficient than the naive approach.
