Redesign the solution in the following manner:

1. Create a menu and ask the user which of the following conversions they wish to perform:

a. Miles to kilometers

b. Gallons to liters

c. Dollars to GBP

d. Pounds to kilograms

e. Inches to centimeters

f. Fahrenheit to Celsius

2. Your program must raise an exception if the user chooses any item not on the menu presented. Along with raising an exception, write the code to handle this exception. (LO 5)

3. Once the user has chosen a menu item the program should:

a. Ask the user for a value to convert. Refer to the input validations in Lab 3. Your program must raise and exception, and handle the exception, if an input errors occurs.

b. Perform the conversion and write the original value, the original unit, the converted value, and the converted unit to an output file named conversions.txt.

c. Repeat steps a and b 4 times (in a loop)
