Problem Statement

In Tower Research Capital's technical coding assessment, candidates are evaluated on clean algorithmic problem-solving for "Unique Binary Search Trees".

Given standard input parameters adhering to Math principles, design an optimal algorithm that satisfies all constraints and handles boundary test scenarios efficiently.

Ensure your implementation minimizes memory overhead and executes within the allotted online assessment time limits.

Input Format

  • The first line specifies the dimensions or count of test elements N.
  • The subsequent line(s) contain the input array, string, or graph representation.

Output Format

  • Print the computed result adhering to the required return format.

Constraints

  • 1 <= N <= 10^5
  • -10^9 <= element[i] <= 10^9
  • Time Limit: 2.0 seconds
  • Memory Limit: 256 MB

Edge Cases

  • Empty or single-element input
  • Input containing maximum or minimum boundary values
  • Uniform elements or all-negative test cases

Sample Test Cases

Example 1

Input

nums = [1, 2, 3, 4, 5], k = 3

Output

3

Explanation

Applying the optimal Math approach yields the expected solution 3.

Candidate Instructions

  • Identify the core invariant related to Math.
  • Verify edge cases including empty inputs and extreme bounds.
  • Optimize time complexity before submitting.
Time:O(log N)
Space:O(1)
Approach:Leverage Math combined with Dynamic Programming, Tree, Binary Search Tree, Binary Tree to process the input in optimal O(log N) time complexity.
