Some roses, a hamburger, the AK47, and a puddle Book

A bunch of mostly elementary programming puzzles, which I wanted to rummage for interview questions. I think that the authors of a programming book who advise their readers, "Make Your Arrays a Little Larger Than Necessary ' Off-by-one errors are a particularly subtle and tricky class of bugs. Clear thinking and discipline are the right way avoid them. [sic] But thinking is hard and memory is cheap. We find it a useful crutch to define arrays one or two elements larger than should be necessary so as to minimize the consequences of any off-by-one error," should be drawn and quartered (or fifthed).
