So, if $$k$$ is $$O(n)$$ ,CountSort becomes linear sorting, which is better than comparison based sorting algorithms that have $$O(n log n)$$ time complexity. Step 4 is a subpart of step 3, as after swapping 1 with 10, again a recursive call of max_heapify(Arr, 3) will be performed , and 1 will be swapped with 9. Alice and Strings. Max Heap: In this type of heap, the value of parent node will always be greater than or equal to the value of child node across the tree and the node with highest value will be the root node of the tree. Please refresh the page or try after some time. 3: 6: Since Radix Sort depends on digits or letters, Radix Sort is much less flexible than other sorts. Suppose there are N elements stored in array Arr. Step 2: 8 is disconnected from heap as 8 is in correct position now and. The constant for Radix sort is greater compared to other sorting algorithms. If at every instant we have to add a new job in the queue, we can use insert_value operation as it will insert the element in O(log N) and will also maintain the property of max heap. 1) Initially we will build a max heap of elements in Arr. LEVEL: Easy, ATTEMPTED BY: 6423 We will run the above function on remaining nodes other than leaves as leaf nodes are 1 element heap.
