Check 3.6
Write a function called changeLowercase(s) which takes in a string s and replaces every lowercase letter with the character of the ord one less than it and returns the result. For example, "ABdDEF" changes to "ABcDEF" because the ord of "d" is 100, 100 - 1 is 99, and the ASCII character corresponding to 99 is "c".
Note: Since there are no letters below a, an a will become a back tick. And that's okay!

assert(changeLowercase("dcb") == "cba")
print("passed!")
