Whether you are writing a real-time scheduler, merging K-sorted lists, or acing your next technical interview, the humble heap_adjuster will be your most reliable tool.

def heap_adjuster(arr, n, i): """ Adjusts the heap rooted at index i. arr: The list representing the heap n: The size of the heap i: The index of the node to adjust """ largest = i # Assume current root is largest left = 2 * i + 1 right = 2 * i + 2 # Check if left child exists and is greater than root if left < n and arr[left] > arr[largest]: largest = left heapadjuster
