Write a program that accepts a number and then multiplies that number by three. Here are some examples of input and expected output.

Write a function called getSumOfProds that will take two arrays of the same size and their lengths, and return the sum of the products of the individual elements.

For example:

$[121]$ x $[121]=1$x$1+2$x$2+1$x$1=1+4+1=6$
