Battery Round-Trip Efficiency

Problem

Compute battery round-trip efficiency as the geometric mean of charge and discharge efficiencies: sqrt(charge_eff * discharge_eff).

Both efficiencies are fractions between 0 and 1.

Hint

The geometric mean is the efficiency of a full charge-discharge cycle.

case 1

in: [0.9,0.9]

expected: 0.9

case 2

in: [0.81,1]

expected: 0.9

case 3

in: [0.8,0.9]

expected: 0.8485281374238571

case 4

in: [0,0.5]

expected: 0
