Problem 48175. Cipher or Decipher the number according to the second input - 3 keys - order [1 2 3 2 1 2 3 ......]

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
