A REPL is nice too: (reduce + (range 366))

  Python: reduce (operator.add, range(366))
  • tome 17y ago
    or sum(range(366))

      didn't even think of that one! :)

        or plain math: n(n+1)/2

          How quickly can you generalize the plain math formula to these sequences: http://www.research.att.com/njas/sequences/index.html http://www.research.att.com/njas/sequences/index.html

      (sum (range 1 365)) assuming you defined these already; I have them in my utils library ;-) (defun range (start end) (loop for x from start to end collecting x)) (defun sum (sequence) (reduce #'+ sequence))
