要保证接口为binSearch(array, target),所以此处使用了Arrays.copyOfRange()--导致造成了额外的空间消耗(创建新的数组)。 Version 2: //注意这种切换接口的方式publicstatic<TextendsComparable<?superT>>intbinSearch_JDK(T[] arr, T element) {//With RecursionreturnbinSearch_JDK(arr, 0, arr.length - 1...
Notice how there's no way that your function could ever return true because every time you terminate the recursion, you're returning false? And the problem is in your first check. You say that "all the values in the tree are less than the integer." Well, in an empty tree, all the ...
I have successfully written a method to print the values of all the nodes in the subtree rooted at a given node (code pasted below under the label "Working Code"). However, this printTree method is in the Main class (as opposed to being in the Node class itself). I am wondering if ...

Some of the problems in this article use plain binary trees, and some use binary search trees. In any case, the problems concentrate on the combination of pointers and recursion. (See the articles linked above for pointer articles that do not emphasize recursion.) ...
The last page covered some simple examples of recursion, which could have been coded with loops just as easily. In other cases, using recursion is considerably more 'natural' than using loops. The Algorithm You are given an array sorted in increasing order and would like to find the location...

Note:If a tree has more than one mode, you can return them in any order. Follow up:Could you do that without using any extra space? (Assume that the implicit stack space incurred due to recursion does not count). 现有一个可以包含重复元素的二叉查找树,该二叉查找树满足所有左节点的值均小于...
Recursion 解法Intuition:这道题呐,其实Recursion的想法很容易想,我们依次遍历每个数,把这个数当初Root,那么比这个数小的数都当成左子树,比这个数大的数都当成右子树。退出Recursion的条件自然是左边界大于右边界啦。Edge Case:if (n <= 0){ return new ArrayList<TreeNode>(); } ...
