heap.Interface

// The Interface type describes the requirements // for a type using the routines in this package. // Any type that implements it may be used as a // min-heap with the following invariants (established after // Init has been called or if the data is empty or sorted): // // !h.Less(j, i) for 0 <= i < h.Len() and 2*i+1 <= j <= 2*i+2 and j < h.Len() // // Note that Push and Pop in this interface are for package heap's // implementation to call. To add and remove things from the heap, // use heap.Push and heap.Pop. type Interface interface { sort.Interface Push(x any) Pop() any }

heap.Fix

// Fix re-establishes the heap ordering after the element at index i has changed its value. // Changing the value of the element at index i and then calling Fix is equivalent to, // but less expensive than, calling Remove(h, i) followed by a Push of the new value. // The complexity is O(log n) where n = h.Len(). func Fix(h Interface, i int)

heap.Init

// Init establishes the heap invariants required by the other routines in this package. // Init is idempotent with respect to the heap invariants // and may be called whenever the heap invariants may have been invalidated. // The complexity is O(n) where n = h.Len(). func Init(h Interface)

heap.Pop

// Pop removes and returns the minimum element (according to Less) from the heap. // The complexity is O(log n) where n = h.Len(). // Pop is equivalent to Remove(h, 0). func Pop(h Interface) any

heap.Push

// Push pushes the element x onto the heap. // The complexity is O(log n) where n = h.Len(). func Push(h Interface, x any)

heap.Remove

// Remove removes and returns the element at index i from the heap. // The complexity is O(log n) where n = h.Len(). func Remove(h Interface, i int) any
