Chapter 3, Problem 10PS
Explanation of Solution
Consider the following grammar:
<S> -> <A><B><C>
<A> -> a <A> | a
<B> -> b <B> | b
<C> -> c <C> | c
In the given case, <A><B><C> generates all sentences which consists one or more than one a's followed by one or more than one b's followed by one or more than one c's.
<A> generates one or more than one consecutive a's.
<B> generates one or more than one consecutive b's.
<C> generates one or more than one consecutive c's...
