# Problem7: Translate fom and to UNICODE
# Enter a string to hide in uppercase: HIDE
# Secret Message: 3547890
# Original Message: HIDE
# The code works only for upper case char because their
# unicode range is in between 65 and 90
# After changes in line 16 and 27 (adding and removing 23)
# it works for both lower and upper cases - although the
# resulting code is not exactly the one from unicode
# I changed it to run with 2 variables - one for changing back
# to normal string and one to store unicode values

# Input - Enter a string to hide in uppercase
