You will be given an input number. You have to figure out the cipher keys and match it with given input and cipher it and decipher it according to second input.
The following are not real keys, just an example:
ref =   [0 1 2 3 4 5 6 7 8 9];
key_1 = [1 2 3 4 5 6 7 8 9 0];
key_2 = [3 4 5 6 7 8 9 0 1 2];
key_3 = [2 3 4 5 6 7 8 9 0 1];
For example, if x = 12321, y = 1:
output = 25552
(Hint: index: 1 -> key 1, 2 -> key 2, 3 -> key 3, 4 -> key 2, 5 -> key 1, 6 -> key 2, 7 -> key 3, 8 -> key 2, 9 -> key 1, ...)
Or, if x = 25552, y = 2:
output = 12321

I don't understand. Isn't decyp() supposed to be called with 2 arguments? All the the test-suite problems call it with 1 argument, and therefore don't indicate whether it is supposed to cipher or decipher.

Lincoln Poon on 22 Jan 2021

Other problems of this type (cipher/decipher from 2nd input) are called with 2 arguments.
If that was the intended way of solving this question, someone please fix the test suite.

The problem description has been cleaned up. Also, the test suite now calls the function with two inputs, as mentioned by William.
Based on a commented-out solution by Lincoln Poon, the problem appears to now be functional.
