Question
You guys use AI tool to answer. Last time I found plagiarism and AI detection in my answer. Now If you will use these things I'll surely give multiple downvotes and will report ⚠️ sure.

Transcribed Image Text:The Quantum Access Authentication System of a futuristic space station uses
complex algorithms to validate access codes. Each access code is a sequence of
digits, and the validation process involves intricate mathematical operations.
The validation mechanism is described as follows:
Take the sum of the digits at odd positions from left to right.
Take the product of the digits at even positions from left to right.
If the absolute difference between the results from step 1 and step 2 is a prime
number, the access code is considered valid; otherwise, it is invalid.
Example 1:
Consider the access code 13579246.
Step 1. Take the sum of the digits at odd positions from left to right.
1+5+9+2=17
Step 2. Take the product of the digits at even positions from left to right.
3*7*2*6=252
Step 3. If the absolute difference between the results from step 1 and step 2 is a prime
number.
17-252) 235 (prime)
Access code 13579246 is valid.
Example 2:
Now, let's examine the access code 86420137.
Step 1. Take the sum of the digits at odd positions from left to right.
8+4+0+3=15
Step 2. Take the product of the digits at even positions from left to right.
6*2*1*7=84
Step 3. If the absolute difference between the results from step 1 and step 2 is a prime
number.
115-841=69 (not prime)
Access code 86420137 is invalid.
Example 3:
Finally, let's check the access code 24681357.
Step 1. Take the sum of the digits at odd positions from left to right.
2+6+1+5=14
Step 2. Take the product of the digits at even positions from left to right.
4*8*3*7=672
Step 3. If the absolute difference between the results from step 1 and step 2 is a prime
number.
114-6721 = 658 (not prime)
Access code 24681357 is invalid.
Your task is to write a program that reads access codes from user input and classifies
them as "valid" or "invalid." The program should have two arrays for valid and invalid
access codes, initially empty. The array sizes should be set to 20, assuming the user
will enter at most 20 access codes. The program should start asking for an integer
from the user, representing the access code. If the access code is valid according to
the validation steps, it should be added to the "valid codes" array. If the code is invalid,
it should be added to the "invalid codes" array. If the user enters the code 0, the
program should display the valid and invalid codes arrays and stop. Error handling for
non-integer inputs is not required.
