Problem 1a:

In this problem, you are going to create a function that takes 4 inputs and returns a structure. The function has the format: Function structure = Construct ( brand, color, VIN, operational ) There are some requirements for this function:

1) If the number of inputs is not 4, display Error: Incorrect number of field values provided.

2) The input brand must be string, if not, display Error: brand must be string.

3) The input color must be string, if not, display Error: color must be string.

4) The input VIN is a mix of string and numbers. Its 6 digits in total. The first digit will be a character V, the others will be numbers. You can use isstrprop() function. Use isstrprop(array, alpha) or isstrprop(array,digit) to check the string. For example:

If the format is not correct, display Error: VIN format is not correct.

5) The input operational must be Boolean value, True or False. If not, display Error: operational must be Boolean.

6) When the structure is successfully created, display information recorded!

Problem 1b:

Use the function you have write to create an array of structure, which includes the following information:

Brand	color	VIN	operational
Honda	White	V12345	true
BMW	Black	V23451	false
Buick	Red	V34512	false
Mazda	Silver	V45123	true
Audi	Black	V51234	true

For example, create a car structure with the construct function: car1 = construct(Honda, White, V12345, true). All the structure will be put into an array.

Problem 1c

Use for loop to filter all the cars whose operational is True and display their VIN.
