CODES
+======+

Each person in Italy has an unique identifying ID code issued by the national tax office after the birth registration: the Fiscal Code (Codice Fiscale). Check the Resources tab for more info on this.

Given an object containing the personal data of a person (name, surname, gender and date of birth) return the 11 code characters as a string following these steps:

Generate 3 capital letters from the surname, if it has:
At least 3 consonants then the first three consonants are used. (Newman -> NWM).
Less than 3 consonants then vowels will replace missing characters in the same order they appear (Fox -> FXO | Hope -> HPO).
Less than three letters then "X" will take the third slot after the consonant and the vowel (Yu -> YUX).

Generate 3 capital letters from the name, if it has:
Exactly 3 consonants then consonants are used in the order they appear (Matt -> MTT).
More than 3 consonants then first, third and fourth consonant are used (Samantha -> SNT | Thomas -> TMS).
Less than 3 consonants then vowels will replace missing characters in the same order they appear (Bob -> BBO | Paula -> PLA).
Less than three letters then "X" will take the the third slot after the consonant and the vowel (Al -> LAX).

Generate 2 numbers, 1 letter and 2 numbers from date of birth and gender:
Take the last two digits of the year of birth (1985 -> 85).
Generate a letter corresponding to the month of birth (January -> A | December -> T) using the table for conversion included in the code.
For males take the day of birth adding one zero at the start if is less than 10 (any 9th day -> 09 | any 20th day -> 20).
For females take the day of birth and sum 40 to it (any 9th day -> 49 | any 20th day -> 60).

EXAMPLE:

fiscalCode({
  name: "Helen",
  surname: "Yu",
  gender: "F",
  dob: "1/12/1950"
}) ➞ "YUXHLN50T41"

fiscalCode({
  name: "Mickey",
  surname: "Mouse",
  gender: "M",
  dob: "16/1/1928"
}) ➞ "MSOMKY28A16"

Binary loop
____
Write a function that takes a binary number as an input and shifts each bit by one to the right or left while looping on itself like a circle.
Make a delay of one second between each shift.

Example:
Input : 00101100

Output: (shifting to the right)
First loop: 00010110
Second loop: 00001011
Third loop: 10000101

SPEED
+====+
If the lowest speed of a car was written as (50) instead of zero and the highest speed (250) instead of (200) then how can we know what speed we are at if the speedometer reads, for example, 100?
_________
Write a program that takes two arrays of length 2 each, and a number to be converted based on the inputted arrays. The first array is like the scale, the second array is what should be converted based on the first array, and the third argument is the number to be converted.

example:
function([1,100], [50,150], 60) //output => 10

function([1,100], [50,150], 80) //output => 30
