Very Easy 4-lines Java Code

  • 1

    My accepted Java code.

    public int minDepth(TreeNode root) {
         if(root == null) return 0;
         if(root.left == null) return 1 + minDepth(root.right);
         if(root.right == null) return 1 + minDepth(root.left);
         return 1+Math.min(minDepth(root.left), minDepth(root.right));
