I second this. I did undergrad and grad pure math at UW, and a lot of comp sci electives. The faculty was phenomenal. I learned so much, and not just of the subject material. I learned so much about how to think during some brilliant lectures. You want some mental exercise that will make programming seem easy by comparison? Get a pure math degree at UW. And take all the hard classes. Nor was I bored in even the intro C Sci classes. There were typically other experienced folks taking the classes with me, and some projects open-ended enough to let them challenge themselves. I saw some guys build an animated 3D vector projection from scratch in CSE 143, and in CSE 373, during a speed competition, I remember someone taking apart and rewriting scanf.
