Compilers_BottomUpParsing
Consider the grammar: S → aSa  bSb  aa  bb A shiftreduce parser works by identifying the handle of each rightsentential form and replacing it by the head of the corresponding production. In this question, we indicate the handle of a rightsentential ... above grammar with the handle properly marked? a) abab[aababa] b) ababaS[ababa] c) ababbS[bbaba] d) abab[bSb]baba

An undorected graph $G = (V, E)$ is said to be $k$colourable if there exists a mapping $c: V \rightarrow \{1, 2, \dots k \}$ such that for every edge $\{u, v\} \in E$ we have $c(u) \neq c(v)$. Which of the following statements is FALSE? ... is the maximum degree in $G$ There is a polynomial time algorithm to check if $G$ is 2colourable If $G$ has no triangle then it is 3colourable
