Write a program that implements this definition of square numbers:
square(1) = 1 square(N) = square(N-1) + 2N -1
Make a complete program similar to TriangleTester.java given in the chapter.
Aside: where did this crazy definition of square come from?
Easy: this is just algebra:(N-1)2 = N2 - 2N + 1
rearrange to get:N2 = (N-1)2 + 2N - 1
Square numbers are also mentioned in the quiz for this chapter.
