To construct the LALR (1) parsing table, we use the canonical collection of LR (1) items. In the LALR (1) parsing, the LR (1) items which have same productions but different look ahead are combined to form a single set of items. LALR (1) parsing is same as the CLR (1) parsing, only difference in the …
