    257 - Binary Tree Paths\.

    Easy

    Given the root of a binary tree, return all root-to-leaf paths in any order.

    A leaf is a node with no children.

    Example 1:

    Input: root = 1,2,3,null,5

    Output: "1->2->5","1->3"

    Example 2:

    Input: root = 1

    Output: "1"

    Constraints:

    • The number of nodes in the tree is in the range [1, 100].

    • -100 <= Node.val <= 100
