Draw the derivation tree corresponding to the derivation in Example 5.1.
Example 5.1
The grammar $G = (${$S$}, {$a, b$}$, S, P),$ with productions
$S\rightarrow aSa$
$S\rightarrow bSb$
$S\rightarrow \lambda$
is context-free. A typical derivation in this grammar is
$S\Rightarrow aSa\Rightarrow aaSaa\Rightarrow aabSbaa\Rightarrow aabbaa.$
