An area of memory used for {dynamic memory
allocation } where blocks of memory are allocated and freed in
an arbitrary order and the pattern of allocation and size of
blocks is not known until {run time }. Typically , a program
has one heap which it may use for several different purposes .
Heap is required by languages in which functions can return
arbitrary data structures or functions with {free variables }
see {closure }). In {C } functions {malloc } and {free } provide
access to the heap .
Contrast {stack }. See also {dangling pointer }.
2 . A data structure with its elements partially
ordered (sorted ) such that finding either the minimum or the
maximum (but not both ) of the elements is computationally
inexpensive (independent of the number of elements ), while
both adding a new item and finding each subsequent
smallest /largest element can be done in O (log n ) time , where n
is the number of elements .
Formally , a heap is a {binary tree } with a key in each {node },
such that all the {leaves } of the tree are on two adjacent
levels ; all leaves on the lowest level occur to the left and
all levels , except possibly the lowest , are filled ; and the
key in the {root } is at least as large as the keys in its
children (if any ), and the left and right subtrees (if they
exist ) are again heaps .
Note that the last condition assumes that the goal is finding
the minimum quickly .
Heaps are often implemented as one -dimensional {arrays }.
Still assuming that the goal is finding the minimum quickly
the {invariant } is
heap [i ] <= heap[2*i] and heap[i] <= heap[2*i+1] for all i,
where heap [i ] denotes the i -th element , heap [1 ] being the
first . Heaps can be used to implement {priority queues } or in
sort } algorithms .
