Description

Xiao Ying is a third-year pharmacy student who secured an internship opportunity at a hospital pharmacy during the summer break.

During her internship, Xiao Ying's solid professional foundation earned consistent praise from the doctors. Upon learning that she had achieved excellent grades in Introduction to Computing, the department head assigned her an additional task: decrypting a list of wounded soldiers' names that had been encrypted during the Anti-Japanese War.

After thorough research, Xiao Ying discovered the following encryption rules (with an example of "original text -> encrypted text" in parentheses):

1. All characters in the original text are cyclically shifted three positions to the left in the alphabet (e.g., dec -> abz).
2. The text is stored in reverse order (e.g., abcd -> dcba).
3. The case of each letter is inverted (e.g., abXY -> ABxy).

Input Format

An encrypted string (length less than 50 and containing only uppercase and lowercase letters).

Output Format

Output the decrypted string.
