# Path in Matrix

Problem Description

Given N x N matrix filled with 0, 1, 2, 3.
Find whether there is a path possible from source to destination, traversing through blank cells only.
You can traverse up, down, right, and left. Return a single integer 1 if a path exists, otherwise 0.

• A value of cell 1 means Source.
• A value of cell 2 means Destination.
• A value of cell 3 means Blank cell.
• A value of cell 0 means Blank Wall.
Note: there are an only a single source and single destination(sink).

Problem Constraints
2 <= N <= 103
0 <= Ai, j <= 3

Input Format
The first argument is the 2D integer array A.

Output Format
Return a single integer 1 if a path exists, otherwise 0.

Example Input
Input 1:

``````A = [[1, 0], [0, 2]]
``````

Input 2:

``````A = [[1, 3], [3, 2]]
``````

Example Output
Output 1:

``````0
``````

Output 2:

``````1
``````

Example Explanation
Explanation 1:

``The source is blocked by walls on all its sides. So, there is no way to reach the destination.``

Explanation 2:

``````We can take any possible path to reach the destination from the source.
``````

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
