Class hours: MW 11:00am-12:15pm, 380-380Y. However, an SLR(1) parser will compute Follow(T) = { + ) $ } and Follow(V) = { = } and thus can distinguish which reduction to apply depending on the next input token. It is a coincidence in the example above that the non-terminal program has the same name as a union member. GarbageCollection. Instructor: Fredrik Kjolstad Slide design by Prof. Aiken CS 143 Lecture 5 23 Cool Example (Cont. Students typically apply to the Coterm program during their senior year, and CS Foundations may be waived, if equivalent coursework has been completed at another institution.
