A binary search tree uses the definition: that for every node,the node to the left of it has a less value(key) and the node to the right of it has a greater value(key).
Where as the heap,being an implementation of a binary tree uses the following definition:
If A and B are nodes, where B is the child node of A,then the value(key) of A must be larger than or equal to the value(key) of B.That is,
key(A) ≥ key(B).

How to determine an almost complete binary tree is a heap?
A binary heap is defined as follows: # It it an "almost" complete binary tree. That is, the bottom level of a heap of height h is partially filled from left to right, and may only have from 1 to 2h nodes. This may make some of the nodes at level h-1 into leaf nodes. So a binary heap of height h may have anywhere from 2h to 2h+1-1 nodes. # It satisfies the heap property. Each node has some ordered value associated with it, like a real number. The heap property asserts that a parent node must be greater than or equal to both of its children. A binary heap is easily represented using an array, let's call it A[1..length(A)]. The size of the heap will be called heap-size(A) (obviously heap-size(A)
What is a heap?
Answer:- A sorting algorithm that works by first organizing the data to be sorted into a special type of binary tree called a heap. The heap itself has, by definition, the largest value at the top of the tree, so the heap sort algorithm must also reverse the order. It does this with the following steps:1. Remove the topmost item (the largest) and replace it with the rightmost leaf. The topmost item is stored in an array.2. Re-establish the heap.3. Repeat steps 1 and 2 until there are no more items left in the heap.The sorted elements are now stored in an array.A heap sort is especially efficient for data that is already stored in a binary tree. In most cases, however, the quick sort algorithm is more efficient.GOURAV KHARE (CHANDIGARH)gouravsonu89@gmail.com
What will be the difference in running time of the heap sort algorithm if you start to apply heap sort with an array elements rather than max heap elements?
The heap sort algorithm is as follows: 1. Call the build_max_heap() function. 2. Swap the first and last elements of the max heap. 3. Reduce the heap by one element (elements that follow the heap are in sorted order). 4. Call the sift_down() function. 5. Goto step 2 unless the heap has one element. The build_max_heap() function creates the max heap and takes linear time, O(n). The sift_down() function moves the first element in the heap into its correct index, thus restoring the max heap property. This takes O(log(n)) and is called n times, so takes O(n * log(n)). The complete algorithm therefore equates to O(n + n * log(n)). If you start with a max heap rather than an unsorted array, there will be no difference in the runtime because the build_max_heap() function will still take O(n) time to complete. However, the mere fact you are starting with a max heap means you must have built that heap prior to calling the heap sort algorithm, so you've actually increased the overall runtime by an extra O(n), thus taking O(2n * log(n)) in total.
Application of binary tree in data structure?
1) the complexity of insertion,deletion and searching operation is depend on the height of the tree. i.e. if height is n(for skew binary tree) then complexity is O(n) . 2) difficult to get the sorted list from the binary tree.which is easy for BST.
What is the difference between binary heap and binomial heap?
The difference between Binomial heap and binary heap is Binary heap is a single heap with max heap or min heap property and Binomial heap is a collection of binary heap structures(also called forest of trees).

What is leftist-heap?
A leftist heap is a type of heap data structure that is a variant of a binary heap. It supports all the standard heap operations (insertion, deletion, and merging) with performance guarantees similar to binary heaps, but it maintains a leftist property that ensures that the left child has a shorter or equal path to the nearest null (empty) node than the right child. This property helps to improve the efficiency of merge operations in leftist heaps compared to binary heaps.
What is best algorithm for searching?
It depends on how the data is arranged. In case it is an array, use linear search or binary search or interpolation search according as the array is sorted or not and based on the distribution of data. If some other data structures are used (like heap) for making data retrieval efficient, other algorithms exist.
What is the definition of heap?
heap sort is sorting the elements afta piling them in a binary tree format called heap. it is solved by interchanging the root node with the right most element in the tree.
What is the difference between a compost heap and a compost pit?
A compost heap is a pile of composting material that is in a pile on the ground. A compost pit is dug into the ground and the composting material is placed in it.
What is the difference between compost pile and compost pit?
A compost pile is compost in a pile or heap. a compost pit is compost in a pit or hole in the ground.
