注意事项:

参考代码:

s = input()

t = ""

for i in s:

    if ord('a') <= ord(i) <= ord('z'):

        t += chr(ord(i)-32)

    elif ord('A') <= ord(i) <= ord('Z'):

        t += chr(ord(i)+32)

t = t[::-1]

l = ""

for i in t:

    if ord('a') <= ord(i) <= ord('z'):

        l += chr((ord(i)+3-97)%26+97)

    elif ord('A') <= ord(i) <= ord('Z'):

        l += chr((ord(i)+3-65)%26+65)

print(l)
