How cold is it outside? The temperature alone is not enough to provide the answer. Other factors including wind speed, relative humidity, and sunshine play important roles in determining coldness outside. In 2001, the National Weather Service (NWS) implemented the new wind-chill temperature to measure the coldness using temperature and wind speed. The formula is

t_wc = 35.74 + 0.6215t_a - 35.75v^0.16 + 0.4275t_av^0.16

where t_a is the outside temperature measured in degrees Fahrenheit, v is the speed measured in miles per hour, and t_wc is the wind-chill temperature. The formula cannot be used for wind speeds below 2 mph or temperatures below -58F or above 41F.

Requirements

Write a Go program that prompts the user to enter a temperature between -58F and 41F and a wind speed greater than or equal to 2 then displays the wind-chill temperature. If the user enters an invalid number due it being out of range or not a number, prompt the user again until they enter a valid value. Output two digits past the decimal place (hundreths of F).

Add a flag to the program called "-table" that displays a table instead of prompting. The table should have the same bounds and format as the above table in the Overview section except that it should show the wind chill to the tenths place.

Do not use any library other than the Go standard library.
