The initial DFA state I0 we computed is the ε-closure of the set consisting of item

S → •E

Recall the stage in the closure

s = { [S → •E, $] , [E → •E + (E), $] , [E → •int, $] }

The NFA states and transitions required are

An LR(1) item is a pair [X → α•β, a] where X → αβ is a production and a∈T (terminals) is look-ahead symbol. The model uses a set of LR(1) items to represent each parser state. The model is called the canonical collection (CC) of set of LR(1) items.
