Description
For elephants, we use the "EMI" (Elephant Mass Index) to assess their health status.
To calculate an elephant's EMI, we use the formula below:
w = weight, h = height.
Elephants perform calculations using the double data type, and the output should be formatted to 6 decimal places.
You don't need to worry about the units; just calculate using the given values.
Input
The first line contains two integers: w, and h, respectively.
1 ≤ h ≤ w ≤ 10000
Output
Output the answer following the specified formatting rules.
Note that you do NOT need to print '\n' at the end of the output.

Description
Since the EECS was leaked by an impostor among the elephants, they decided to reinforce the rule by adding one more step.
The rules of EECS-2 are as follows:
- Shift each character in the string
sbykpositions in the alphabetical order. For example,
Shifting 'a' by 3 positions results in 'd'.
Shifting 'w' by 6 positions results in 'c'. - Convert every character in the new string from lowercase to uppercase. For example,
'g' becomes 'G'. -
Reverse the entire string. For example,
"ELEPHANT" becomes "TNAHPELE".
To prove that you are not the impostor, please encrypt the string of length 5 and a shift distance k using EECS-2.
You can try solving the problem without needing to know the exact ASCII values of the letters.
Input
The first line contains a single integer k.
1 ≤ k ≤ 26
The second line contains a single string s.
It is guaranteed that all characters in s are lowercase letters and the length of the string is 5.
Output
Output the encrypted string.
Note that you do NOT need to print '\n' at the end of the output.
