Leetcode Solutions

Min-Heap Approach for Finding K Largest Elements

  1. Initialize a min-heap that will store pairs of (element value, original index).
  2. Iterate over the array, adding each element to the min-heap.
  3. If the heap size exceeds k, remove the smallest element from the heap.
  4. Once all elements have been processed, extract the elements from the heap and store them in a list.
  5. Sort the list by the original indices of the elements.
  6. Extract the sorted elements from the list to form the final subsequence.
