Harmonic numbers. Write a program Harmonic that contains three static methods harmonic(), harmonic Small(), and harmonic Large() for computing the harmonic numbers. The harmonic Small() method should just compute the sum (as in Program 1.3.5), the harmonic Large() method should use the approximation Hn = loge
 (the number
 = 0.577215664901532... is known as Euler’s constant), and the harmonic() method should call harmonic Small() for n <>
