heap adt code example

Example 1: heap

A heap is a tree-based data structure in which all the nodes of the tree are in a specific order. For example, if is the parent node of , then the value of follows a specific order with respect to the value of and the same order will be followed across the tree.

Example 2: heap

void max_heapify (int Arr[ ], int i, int N)
    {
        int left = 2*i                   //left child
        int right = 2*i +1           //right child
        if(left<= N and Arr[left] > Arr[i] )
              largest = left;
        else
             largest = i;
        if(right <= N and Arr[right] > Arr[largest] )
            largest = right;
        if(largest != i )
        {
            swap (Arr[i] , Arr[largest]);
            max_heapify (Arr, largest,N);
        } 
     }
