解题思想:
二叉树的最大深度即为左子树的深度与右子树深度的较大值 + 1,而求子树的深度一样可以用这个方法计算。 一直递归到空节点结束。
代码:
var maxDepth = function(root) { if (!root) return 0; if (root.left === null && root.right === null) { return 1; } const leftDepth = maxDepth(root.left) + 1; const rightDepth = maxDepth(root.right) + 1; return Math.max(leftDepth, rightDepth); };
