Array Count Greater Than (Two Dimensional)
Geoffrey Challen // 2020.6.0
Declare and implement a function called countArrayGreaterThan that receives a two-dimensional array of
int values as its first parameter, an int as its second parameter, and returns a count (as an int) of the
number of values in the array that are greater than the passed int.
If the array is null you should return 0.
Note that the array may also be non-rectangular, but no second-level arrays will be null.
