There are three brothers named `A`, `B`, and `C`. The age relationships among them are given by three characters $S_{\mathrm{AB}}, S_{\mathrm{AC}}, S_{\mathrm{BC}}$, which mean the following: * If $S_{\mathrm{AB}}$ is `<`, then $A$ is younger than $B$; if it is `>`, then $A$ is older than $B$. * If $S_{\mathrm{AC}}$ is `<`, then $A$ is younger than $C$; if it is `>`, then $A$ is older than $C$. * If $S_{\mathrm{BC}}$ is `<`, then $B$ is younger than $C$; if it is `>`, then $B$ is older than $C$. Who is the middle brother, that is, the second oldest among the three? ## Constraints * Each of $S_{\mathrm{AB}}, S_{\mathrm{AC}}, S_{\mathrm{BC}}$ is `<` or `>`. * The input contains no contradictions; that is, there always exists an age relationship that satisfies all given inequalities. ## Input The input is given from Standard Input in the following format: $S_{\mathrm{AB}}$ $S_{\mathrm{AC}}$ $S_{\mathrm{BC}}$ [samples]

Input #1

< < <

Output #1

B

Since $A$ is younger than $B$, and $B$ is younger than $C$, we can determine that $C$ is the oldest, $B$ is the middle, and $A$ is the youngest. Hence, the answer is `B`.

Input #2

< < >

Output #2
