Caesar cipher is simple encryption techniques where each letter in the message is replaced by a letter some fixed number of positions down the alphabet.

For example, with a left shift of 2, C would be replaced by A, D would become B, and so on.

Letters:

ABCDEFGHIJKLMNOPQRSTUVWXYZ

After applying Caesar cipher of left shift 2:

YZABCDEFGHIJKLMNOPQRSTUVWX

Input

The first line of the input will contain one integer NN (0<N<260 < N < 26), indicating the left shift of the cipher.

The second line will contain a message in all lower case alphabets and spaces. The message will contain at most 100 characters.

Output

Print the message after applying the Ceaser cipher using the specified left shift.
