Grammar

Rule 0     S' -> expression
Rule 1     expression -> expression example expression
Rule 2     expression -> NUMBER

Terminals, with rules where they appear

NUMBER               : 2
error                : 
example              : 1

Nonterminals, with rules where they appear

expression           : 1 1 0

Parsing method: LALR

state 0

    (0) S' -> . expression
    (1) expression -> . expression example expression
    (2) expression -> . NUMBER

    NUMBER          shift and go to state 2

    expression                     shift and go to state 1

state 1

    (0) S' -> expression .
    (1) expression -> expression . example expression

    example         shift and go to state 3


state 2

    (2) expression -> NUMBER .

    example         reduce using rule 2 (expression -> NUMBER .)
    $end            reduce using rule 2 (expression -> NUMBER .)


state 3

    (1) expression -> expression example . expression
    (1) expression -> . expression example expression
    (2) expression -> . NUMBER

    NUMBER          shift and go to state 2

    expression                     shift and go to state 4

state 4

    (1) expression -> expression example expression .
    (1) expression -> expression . example expression

  ! shift/reduce conflict for example resolved as shift
    $end            reduce using rule 1 (expression -> expression example expression .)
    example         shift and go to state 3

  ! example         [ reduce using rule 1 (expression -> expression example expression .) ]
