Having trouble putting algorithm in minipage

I have the following algorithm. Could any one please let me know how I can put it in a minipage?

\begin{algorithm}\small
 {Start}\;
  \eIf{A is bigger than B}{
  \eIf{if A is bigger than C}{
 A;
 }{
C;
 }
}{
\eIf{B is bigger than C}{
B;   }{
C;
}
}
 \caption{A B C comparison}
 \end{algorithm}
