You will be passed in two arrays. 'I' is an array of currents. 'R' is an array of resistances. Values in the same array position correspond to each other. If those two arrays have the same length, return an array of the corresponding voltages, where voltage is found by multiplying the current times the resistance (V=I*R). However, if the arrays are not the same length, or if either array is empty, simply return an empty array.
