Coverage of all Zeros in a Binary Matrix
Easy Accuracy: 29.54% Submissions: 34 Points: 2

Given a binary matrix  having n rows and m columns, your task is to find the sum of coverage of all zeros in the matrix where coverage for a particular 0 is defined as total number of ones around a zero in left, right, up and bottom directions.

Example 1:

Input: matrix = {{0, 1, 0},
{0, 1, 1}, {0, 0, 0}}
Output: 6


Example 2:

Input: matrix = {{0, 1}}
Output: 1


You don't need to read or print anyhting. Your task is to complete the function FindCoverage() which takes the matrix as input parameter and returns sum of coverage of all zeros in the matrix.

Expected Time Complexity: O(n m)
Expected Space Complexity: O(1)

Constraints:
1 <= n, m <= 100
