Make a function count_items (matrix: list, element: int) that gets a two-dimensional integer table as its parameter. The function calculates how many values according to a given item can be found in the table.

count_items(matrix: list, element: int)

m = [[1, 2, 1], [0, 3, 4], [1, 0, 0]]

print(count_items(m, 1))

Print should look like:
