How to use leetcode to print binary tree from top to bottom in golang

This article is about how to use leetcode to print binary trees from top to bottom in golang. I think it is very practical, so I share it with you. I hope you can get something after reading this article.

Each node of the binary tree is printed from top to bottom, and the nodes on the same layer are printed from left to right.

three

/\

9 20

/\

15 7

Return:

[3,9,20,15,7]

Tip:

The total number of nodes 0 {hvv [0] r=append (rreco h.Val) if h. LeftFormnil {q=append (qgrad h.left)} if h.Rightleavnil {q=append (qgrad h.right)} if len (Q) = = 1 {return r} else {qreq [1:]}} return r} is how to print a binary tree from top to bottom in golang.
