Hi Karen! My name is Larry Larmore, CS prof, UNLV. While looking for additional resources for a student, I found your website http://web.cs.wpi.edu/~kal/courses/cs4533/module3/mybuparsing.html which (by amazing coincidence) has a parsing table with the exact same grammar I used for one example in my class! The states even have the same numbers! Anyway, your example has about 5 errors. I have created a corrected version, which I include below. (1) 0 a*(b+c)$ S5 (2) 0 id 5 *(b+c)$ R6 (3) 0 T 3 *(b+c)$ R4 (4) 0 T 2 *(b+c)$ S7 0 T 2 * 7 (b+c)$ S4 0 T 2 * 7 ( 4 (b+c)$ S5 0 T 2 * 7 ( 4 id 5 +c)$ R6 0 T 2 * 7 ( 4 F 3 +c)$ R4 0 T 2 * 7 ( 4 T 2 +c)$ R2 0 T 2 * 7 ( 4 E 8 +c)$ S6 0 T 2 * 7 ( 4 E 8 + 6 c)$ S5 0 T 2 * 7 ( 4 E 8 + 6 id 5 )$ R6 0 T 2 * 7 ( 4 E 8 + 6 F 3 )$ R4 0 T 2 * 7 ( 4 E 8 + 6 T 9 )$ R1 0 T 2 * 7 ( 4 E 8 )$ S11 0 T 2 * 7 ( 4 E 8 ) 11 $ R5 0 T 2 * 7 F 10 $ R3 0 T 2 $ R2 (19) 0 E 1 $ Accept All the best, Larry
