A mathematical alternating harmonic series is given by a formula such as

X = 1 + 1/3 + 1/5 1/6 + 1/7 1/8 + .. + 1/n where 1/n is the last term of the series which includes all the values prior to the value of n.

Write a Visual Basic program to prompt the operator for a positive 4-digit integer n (0001 9999). Then compute the value of the alternating harmonic series to n terms and output the result.
