Private Helper Method

The Calculator class exposes a public method SumOfSquares(int a, int b) that returns a*a + b*b. It must do this by calling a PRIVATE helper method Square(int n) that returns n * n. Do NOT write a Main method.

For SumOfSquares(3, 4) the program prints the output shown in Expected Output.

Expected Output:

25↵

= newline. The output ends with a newline — print one after the last line.
