$.$ Progam#$3$: Simple Traffic Light Simulator

$$ Write a program that simulates simple Traffic Light as follows.

$$ Imagine a pedestrian waiting at a traffic light. The pedestrian must decide

whether it's safe to cross based on the color of the traffic light and whether a

"Walk" signal is on or off. The traffic light can be "green", "yellow", or "red", and

the "Walk" signal can be $"$on$"$ or "off".

$$ Asks the user to input the color of the traffic light $(`"$green$"`,`"$yellow$"`,$ or $`"$red$"`).$

$$ Asks the user if the "Walk" signal is $`"$on$"`$ or $`"$off$"`.$

$$ Decides and prints out what the pedestrian should do: $`"$Wait$"`,`"$Get Ready"$`,$ or

$`"$Cross$"`.$

$$ Rules:

$1.$ If the traffic light is green and the "Walk" signal is on$,$ print $`"$Cross$"`.$

$2.$ If the traffic light is green and the "Walk" signal is off, print $`"$Wait$"`.$

$3.$ If the traffic light is yellow, regardless of the "Walk" signal, print $`"$Get

Ready"$`.$

$4.$ If the traffic light is red, regardless of the "Walk" signal, print $`"$Wait$"`.$

$5.$ If the use types an invalid input, display an $$Input Error message$$

$$ HINTs:

$1.$ Use Boolean expressions with $`$and$`,`$or$`$ to combine conditions.

$2.$ Ensure the program handles different inputs robustly, including case

sensitivity for the inputs $($e$.$g$.,$ "Green", "green", "GREEN" should all be

treated the same$).$ Same applies of $$on$$ & $$off$($On$,$ ON$,$ on $$ Off, OFF, off$)$

$$ Use the $.$lower$()$ to convert all to lower case!

$.$lower$()$ explained:

$$ color $=$ input$($enter color: $).$lower$()$ will convert whatever is

typed to lower case. If user types GReeN, it will be

converted to green. This way, you only have to compare

the choice$/$color with $$green$$ instead of trying all possible

lower$/$uppercase combination.

$3.$ Display a Menu and handle the case if the user type an invalid choice.
