Starting with the procedure MAX-HEAPIFY, write pseudocode for the procedure MIN- HEAPIFY(A, i), which performs the corresponding manipulation on a min-heap. How does the running time of MIN-HEAPIFY compare to t
22.3 Analysis of mergesort InSection 13.10I claimed that mergesort takes time that is proportional ton log n, but I didn't explain how or why. Now I will. Again, we start by looking at pseudocode for the algorithm. For mergesort, it's ...

Sorting: Sorting is used to sort the data in a data structure so we can access the whole data easily. The different sorting algorithm uses different techniques to sort the data. Like Bubble sort, selection sort, merge sort, insertion sort, etc. Answer a...
pseudocode:伪代码 Build_Max_Heap(A): for i = n/2 downto 1 do max_heapify(A,i); 为什么是从i = n/2开始: 我们知道堆所对应的二叉树的叶子结点不需要参与max_heapify的调整。 当用数组表示存储了n个元素的堆时,叶子节点的下标是n/2+1,n/2+2,……,n。

Here is rough pseudocode for a bottoms-up approach to this. The different distances are stored in a 2D matrix and everything in it is initialized; if there isn't a path it's set to a number like -1 or MAX_NUM to avoid getting "junk" when it comes time to run it. (...
