Solving LIS using DP/Binary search.

Problem

Longest increasing subsequence.

Pattern

This problem demonstrates the DP/Binary search pattern.

Approach

Patience sorting with binary search.

Solution 

  // Solution for LIS
// Pattern: DP/Binary search
// O(n log n) time

Complexity

O(n log n) time

Best Practices

  • Identify the pattern before coding — pattern recognition saves time
  • Handle edge cases: empty input, single element, duplicates
  • Use descriptive variable names even in timed interviews
  • Test with the provided examples plus one custom case
