Design a regular grammar to generate the set of all even integers. Design a regular grammar to generate the set of all odd integers. Design a regular grammar to generate the set of all integers beginning with the digit 8 such that the digits are consecutive and even. If a digit is 8, its following digit (if present) will be 0. The set of valid strings is {8, 80, 802,8024, 80246, 802468,...) Design a regular grammar to generate the set...

For each of the following, construct context-free grammars that generate the given set of strings. If your grammar has more than one variable, we will ask you to write a sentence describing what sets of strings you expect each variable in your grammar to generate. For example, if your grammar were: S → EO E → EE CC 0+ EC C+01 We would expect you to say “E generates (non-empty) even length binary strings; O generates odd length binary strings;...
