The puzzle is: "How many integers from 1 to 100 can you form using just the digits in the year (once each) and the operators +, -, *, /, and ^?" (Parentheses are allowed, also.)
And the answer is, "you can write a program in R to enumerate and tally up all the allowable expressions in 36 lines of code". Not even terribly arcane code, either, though I did make use of a recursive loopy thing to avoid repeating a bunch of loops of different sizes.
(You can make 53 of the 100 integers.)
Oh dear god, is that the time?
