Statement

## Goal

This is the year 2021.

In this fun search you will be presented with a grid of numerals comprising only of 0 1 2 from the digits of the year. Each row will be the same length within a test.

Output the total number of '2021's you can find forward, backward, down, and up.

In the example, '2021' appears in the grid 2 times in the up and down directions but is too short to appear forward or backward.
Input
Line 1: An integer N for the number of rows
Next N rows: of input containing the characters 0 1 2 without spaces. ROW lengths are the same within a test.
Output
Line 1 : Total count of the '2021's you can find in the grid, forward backward, down and up.
Constraints
1 ≤ N ≤ 100
1 ≤ ROW length ≤ 30
