  The Zero divisor Graph of a commutative ring $R$, denoted by $\Gamma[R]$, is
a graph whose vertices are non-zero zero divisors of $R$ and two vertices are
adjacent if their product is zero. We consider the zero divisor graph
$\Gamma[\mathbb{Z}_n]$, for any natural number $n$ and find out which graphs
are Eulerian graphs.
