Even your on-topic stuff wasn't really on-topic "-) You can relax - the bank doesn't have a bunch of PIs snooping around to find out what you're up to. What actually happens is that the university sells the list of registered students to various organisations for use in direct-mail campaigns. (defun modexpt (x y n) "computes (x^y) mod n" (cond ((= y 0) 1) ((= y 1) (mod x n)) ((evenp y) (mod (expt (modexpt x (/ y 2) n) 2) n)) (t (mod (* x (modexpt x (1- y) n)) n))))
