) as the parent node of the last node (49).(b) 97>=49, replace the position, and then filter on the last node of N/2 65.(c) 13(d) 13(e) Finally get a heap, 13 is the most decimal we get.Method of adjusting heap (small top heap):A heap with m elements, the output of the top element of the heap, left m-1 elements. Heap bottom elements are fed to the top of the heap, and the heap is destroyed only because the root node does not satisfy the nature of the heap.The root node is exchanged with the smal

is divided into several 1-length subsequence, then the sequence 22 is merged, a number of sequential sequences of 2 are obtained, and then 22 are merged to obtain a number of ordered sequences of 4, then merge them 22, Merge directly into a series. This gets the sort result we want. merge sort from top down : It is in reverse direction from bottom to top. It basically consists of 3 steps: Decomposition: Dividing the current interval into a split point mid = (low + high)/2; Solution: Recursivel

"105-construct Binary tree from preorder and inorder traversal (constructed two-forked trees by sequence and sequence traversal)" " leetcode-interview algorithm classic-java Implementation" "All topic Directory Index" Original title Given Preorder and inorder traversal of a, construct the binary tree. 　　Note:You could assume that duplicates does not exist into the tree.The main effect of the topic A bina

Java interview is often asked for the 8 large sorting algorithm (analysis + program) Classification: 1 Insert Sort (direct insert sort, hill Sort)2 Exchange sort (bubble sort, quick sort)3 Select sort (Direct select sort, heap sort)4) Merge sort5) Allocation sort (cardinal sort)Maximum required secondary space: merge sortMinimum required auxiliary space: heap SortAverage Speed fastest: quick sort Instabili
