Error

Given a Binary Tree of size N, you need to find all the possible paths from root node to all the leaf node's of the binary tree.

**Example 1:**

**Input:**
1
/ \
2 3
**Output: **1 2 #1 3 #
**Explanation: **
All possible paths:
1->2
1->3

**Example 2:**

**Input:
**10
/ \
20 30
/ \
40 60**
Output: **10 20 40 #10 20 60 #10 30 #

**Your Task:**

Your task is to complete the function **Paths()** that takes the root node as an argument and return all the possible path. (All the path are printed '#' separated by the driver's code.)

**Note: **The return type

**cpp: **vector

**java: **ArrayList>

**python: **list of list

**Expected Time Complexity: **O(N).

**Expected Auxiliary Space: **O(H).

**Note: **H is the height of the tree.

**Constraints:**

1<=N<=10^{3}

**Note: **The **Input/Ouput** format and **Example** given, are used for the system's internal purpose, and should be used by a user for **Expected Output** only. As it is a function problem, hence a user should not read any input from the stdin/console. The task is to complete the function specified, and not to write the full code.
