02 第一种解法 使用一个max变量来表示二叉树中的出现次数最多的节点值,使用HashMap来存储每个节点值及其出现的次数,借助一个递归方法,对二叉树中的节点值进行遍历,每次都将max的值进行更新。在遍历完所有节点后,先将最大值添加进ArrayList中,最后再以整型数组作为结果返回。 privateMap<Integer, Integer> map;priva...

For example, if an application uses ArrayList extensively but never uses an ArrayList subclass, treating ArrayList as final could allow FieldSerializer to save 1-2 bytes per ArrayList field. Closures Kryo can serialize Java 8+ closures that implement java.io.Serializable, with some caveats. ...
This stack structure is back by ArrayList. All operations are guaranted constant time performance. package main import "github.com/emirpasic/gods/stacks/arraystack" func main() { stack := arraystack.New() // empty stack.Push(1) // 1 stack.Push(2) // 1, 2 stack.Values() // 2, 1 ...

The first method uses contains() method of ArrayList by first converting given an array to ArrayList, while the second method simply uses a linear search algorithm to search on a Java array. By the way, to make the question more challenging, I usually asked the candidate to write a ...
