Sliding Window vs Brute Force

Sliding window improves over brute force for fixed-size subarray problems by:
Options
  1. 1Using a hash table for constant-time key lookups over the window
  2. 2Sorting the array once before scanning it from left to right
  3. 3Using recursion instead of an explicit loop over the array
  4. 4Reusing the sum from the previous window instead of recomputing
