Java中两个或多个byte数组合并及int类型转数组 // 用list好处是可以未知多个? public static byte[] test(List<byte[]> values) { int lengthByte = 0; for (byte[] value : values) { lengthByte += value.length; } byte[] allBytes = new byte[lengthByte]; int countLength = 0; for (byte[]
Given an array where elements are sorted in ascending order, convert it to a height balanced BST. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more th
题目: Given an array where elements are sorted in ascending order, convert it to a height balanced BST. 题解: 和我上面一篇将有序链表转成二叉排序树中用哈希表解的方法是一样的.基本思路:链表中间那个节点为树的根节点.根节点的左子树节点应该是根节点左边那部分的中间节点,根节点的右节点应该是根节点右边那部分链表的中间节点.后面就依照这个规律依次类推了. public static TreeNode s
