You are given three integers $A$, $B$ and $C$. Find the minimum number of operations required to make $A$, $B$ and $C$ all equal by repeatedly performing the following two kinds of operations in any order: * Choose two among $A$, $B$ and $C$, then increase both by $1$. * Choose one among $A$, $B$ and $C$, then increase it by $2$. It can be proved that we can always make $A$, $B$ and $C$ all equal by repeatedly performing these operations. ## Constraints * $0 \leq A,B,C \leq 50$ * All values in input are integers. ## Input Input is given from Standard Input in the following format: $A$ $B$ $C$ [samples]

We can make $A$, $B$ and $C$ all equal by the following operations:

*   Increase $A$ and $C$ by $1$. Now, $A$, $B$, $C$ are $3$, $5$, $5$, respectively.
*   Increase $A$ by $2$. Now, $A$, $B$, $C$ are $5$, $5$, $5$, respectively.
