# Question: implement a recursive function for computing the nth harmonic number...

###### Question details

Implement a recursive function for computing the n-th Harmonic number:

Hn=∑ni=11i/Hn=∑i=1n1i

.

Here you have some examples of harmonic numbers.

H_{1} =
1

H_{2} = 1 + 1/2 = 1.5

H_{3} = 1 + 1/2 + 1/3 = 1.8333

H_{4} = 1 + 1/2 + 1/3 + 1/4 = 2.0833
