Q$-3$ Write a Python program with a function called harmonic$\_$sum $(n)$ that calculates the sum of harmonic series of up to $n$ numbers, and returns

the result value using recursion.

Harmonic series is defined as $1+\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+$dots $($n terms$)$

Example of program scenario:

Program Prompt: Enter a non$-$negative integer:

User Response: $4$

Program Response: Sum of harmonic series of up to $4$ numbers is $2\mathrm{.}083333333333333$
