I am attempting to write an efficient Python program which can add an integer to
|
|
its reverse. This is quite easy to do in Lisp and Mathematica but (mostly out of
|
|
curiosity) I wanted to see how one might do this in Python. Converting an
|
|
integer to a string and reversing it and converting back is quite easy (although
|
|
not all of these ops are primitives) but the fact that Long integers have the
|
|
letter L appended means that the loop must include moving the L to the end of
|
|
the reversed string prior to summing. Can anyone think of a particularly clever
|
|
way to do this?
