Binary Tree Inorder Traversal--leetcode,inordertraversal原題連結:https://oj.leetcode.com/problems/binary-tree-inorder-traversal/題目大意:中序遍曆二叉樹解題思路:中序遍曆二叉樹,中序遍曆二叉樹的左子樹,訪問根結點,中序遍曆二叉樹的右子樹。非遞迴實現時,用一個棧類比遍曆過程即可。因為需要先遍曆左子樹,所以每個結點先入棧,出棧時訪問。vector<int>

演算法基礎之五(堆排序),演算法基礎之五堆排序堆排序,首先要瞭解一下這裡的堆是什麼,這裡的堆其實就是二叉樹,很形象是不是,完整的二叉樹從頭看起,就是一個三角形,也可以看成一個“堆”。一、數群組轉換成堆 那麼首先要解決的問題就是給數組排序,如何轉換成二叉樹的?轉換方法數組 int a[],包含元素a[0],a[1],a[2],a[3].....等等。轉換成二叉樹:
