The heapsort algorithm is one of the fastest sorting algorithms available. Heapsort developers use Java because it is a good choice for large arrays they know to be in a state unclassified. For the sake of efficiency, a real tree structure is not used. Instead, the tree is formed in its place, right in the matrix. The heapsort algorithm is a “place in the” algorithm, as it does not require additional memory to perform the type .

write the method of exchange. This swap two elements of a package. ” Public static void swap (int [] a, int i, int j) (int tmp = a [j], a [j] = A [i], a [i] = Tmp ;}”"

Enter the heart of the algorithm, the method siftDown. It is used to make both the structure of the pile and make real the type .

Sift great values to the root of the tree and small values to the leaves with Method siftDown. As this method is called several times during the selection process, the node is more consistent with the sifted root node and moved to the end of the matrix. Any node n has a maximum of two children, whose rates are n * 2 1 / n * 2 2. “” Public static void siftDown (int [] a, int start, int end) (int = root initiation, while ;

(root * 2 1
