Problem Statement

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).

Constraints

0 \leq N \leq 26

1 \leq |S| \leq 10^4

S consists of uppercase English letters.

Input

Input is given from Standard Input in the following format:

N
S

Output

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

Sample Input 1

2
ABCXYZ

Sample Output 1

CDEZAB

Note that A follows Z.

Sample Input 2

0
ABCXYZ

Sample Output 2

ABCXYZ

Sample Input 3

13
ABCDEFGHIJKLMNOPQRSTUVWXYZ

Sample Output 3

NOPQRSTUVWXYZABCDEFGHIJKLM

Solution in C (Clang 10.0.0) (judge verdict: Runtime Error)

#include<stdio.h>
#include<string.h>
int main()
{
	int tc;
	scanf("%d",&tc);
	char input[30];
	scanf("%s",input);
	int len = strlen(input);
	for(int i = 0;i<len;i++)
	{
		input[i] += tc;
		if(input[i] > 'Z')
		{
			input[i] -= 'Z'-'A'+1;
		}
		printf("%c",input[i]);
	}
}
