Harmonic Series Sum

You are given an integer (n). Your task is to compute the sum of the first (n) terms of the harmonic series. The harmonic series is defined as:

[ H(n) = \sum_{i=1}^{n} \frac{1}{i} ]

Print the result rounded to 5 decimal places. This problem tests your ability to work with loops and precision in floating-point arithmetic.

inputFormat

The input consists of a single integer (n) ((1 \leq n \leq 10^7)) representing the number of terms in the harmonic series.

outputFormat
