/**
 * **Exercise:** Calculate the harmonic mean of three numbers.
 *
 * The harmonic mean of three numbers a, b, and c is given by the formula:
 * harmonic_mean = (3/((1/a) + (1/b) + (1/c)))
 *
 * **Inputs:**
 * - a (Double): The first number
 * - b (Double): The second number
 * - c (Double): The third number
 *
 * **Outputs:**
 * - harmonic_mean (Double): The calculated harmonic mean
 *
 * **Example:**
 * >>> calculateHarmonicMean(2.0, 3.0, 4.0)
 * 2.769230769230769
 *
 * Hint: To calculate the harmonic mean, you can use the AND operator in conjunction with function calls to the power operator (**) and inverse operator (1/).
