Question: For the simple arithmetic language we studied in class, imag- ine we add a unary operator ~ for negation; that is, ~10 is inter- preted

For the simple arithmetic language we studied in class, imag- ine we add a unary operator ~ for negation; that is, ~10 is inter- preted as number negative ten. The grammar is then -> | + | - | ~ -> 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 The grammar is clearly ambiguous. Reformulate the grammar so that + and - are left-associative and the precedence of ~ is higher than + and -.
