While solving this problem you will need to use the ord () function, which takes a character as its argument and returns an integer called its Unicode value. The Unicode value is the number used inside the computer's memory to store the character. For example, the uppercase letter A has the Unicode value 65, so ord('A') returns 65. As another example, the lowercase letter z has the Unicode value 122, so ord('z') returns 122. Complete the function encode.steps, which takes one argument, message, a non-empty string of upper- case and lowercase letters. The function iterates over the message string one character at a time, computing the difference in Unicode code values between adjacent characters. More specifically, the code of the "earlier" character is subtracted from the code of the "later" character. For example, suppose we have the string "Worf" The respective Unicode values of these characters are 87, 111, 114 and 102. Therefore, the differences are 24 (24-111-87), 3 (3 114-111) and-12 (-12-102-114). The returned string is assembled by inserting the Unicode differences between adjacent characters. Continuing this example, for the argument string 'Worf" the returned value would be the string ' W2403r-12f
