We have a string $S$ consisting of uppercase English letters. Additionally, an integer $N$ will be given. Shift each character of $S$ by $N$ in alphabetical order (see below), and print the resulting string. We assume that `A` follows `Z`. For example, shifting `A` by $2$ results in `C` (`A` $\to$ `B` $\to$ `C`), and shifting `Y` by $3$ results in `B` (`Y` $\to$ `Z` $\to$ `A` $\to$ `B`).

Input is given from Standard Input in the following format: >$N$\ >$S$ #### Constraints - $0 \leq N \leq 26$ - $1 \leq |S| \leq 10^4$ - $S$ consists of uppercase English letters.

Print the string resulting from shifting each character of $S$ by $N$ in alphabetical order.

***For Sample #1:*** Note that `A` follows `Z`.
