Problem $1$

Generate a $3$x$3$ random integer matrix in the range $-8$ to $27$ store it in a variable named matA

a$.$ subtract $4$ from each element of matA, then cube each element.

b$.$ get the minimum and the maximum values of matA. Store them in variables minA and maxA

c$.$ count how many elements of matA are positive, how many are negative, and how many elements are equal to $0.$ Store the results in variables posA, negA, zeroA

d$.$ get the sum and the product of all elements in matA. Store the results in variables sumA and prodA
