6.1 LALR PARSING:

Example:

1.  Construct C={I0,I1,……….,In} The collection of sets of LR(1) items
 

2. For each core present among the set of LR (1) items, find all sets having that core, and
                                            replace there sets by their Union# (clus them into a single term)


I0 →same as previous
I1 → “
I2 → “
I36 – Clubbing item I3 and I6 into one I36 item.
C →cC,c/d/$
C→cCc/d/$
C→dc/d/$
I5 →some as previous
I47 →C→dc/d/$
I89 →C→cC,c/d/$
