Leetcode Solutions

Sliding Window with Hash Map

  1. Initialize a hash map to store the frequency of elements and variables for the current sum and maximum sum.
  2. Iterate through the array using a sliding window of size k.
  3. Add the current element to the sum and update its frequency in the hash map.
  4. If the window size exceeds k, subtract the leftmost element from the sum and decrease its frequency in the hash map.
  5. If an element's frequency drops to zero, remove it from the hash map.
  6. If the hash map size equals k, update the maximum sum if the current sum is greater.
  7. Continue until the end of the array.
  8. Return the maximum sum.
