1. a) Write a switch statement that assigns to the variable lumens the expected brightness of a standard light bulb whose wattage has been stored in watts. Use the following table. Assign-1 to lumens if the value of watts is not in the table. (25 points) b) Write a nested if statement equivalent to the switch statement for the variable lumens. Watts Brightness (in Lumens) 125 15 25 40 215 500 60 880 1000 75 100 1675 Note: Create two functions and for each part of this problem, which take as input the watts and return the brightness in lumens. Don't forget to also display the brightness value
