physical exercise 31.three.5
develop an accumulator-style model of add-to-pi,
Microsoft Office Home And Business 2010, the function
that adds a natural number to pi without using + (see
section ). show the stage that explains what the
accumulator represents.
generalize the function so that it adds two numbers,
Office 2010 Keygen, the first one a natural
number,
Windows 7 Home Basic, without using +. solution
exercising 31.three.6
produce the perform make-palindrome, which accepts a non-empty
list and constructs a palindrome by mirroring the list around the last
item. thus,
Office Pro, if we were to represent the word ``abc'' and apply
make-palindrome, we would get back the representation of
``abcba''. solution
