Difficulty—

You planned a trip using trains and buses. The train fare will be $A$ yen (the currency of Japan) if you buy ordinary tickets along the way, and $B$ yen if you buy an unlimited ticket. Similarly, the bus fare will be $C$ yen if you buy ordinary tickets along the way, and $D$ yen if you buy an unlimited ticket. Find the minimum total fare when the optimal choices are made for trains and buses. ## Constraints * $1 \leq A \leq 1$ $000$ * $1 \leq B \leq 1$ $000$ * $1 \leq C \leq 1$ $000$ * $1 \leq D \leq 1$ $000$ * All input values are integers. ## Input Input is given from Standard Input in the following format: $A$ $B$ $C$ $D$ [samples]

Input #1

Output #1

520

The train fare will be $600$ yen if you buy ordinary tickets, and $300$ yen if you buy an unlimited ticket. Thus, the optimal choice for trains is to buy an unlimited ticket for $300$ yen. On the other hand, the optimal choice for buses is to buy ordinary tickets for $220$ yen.
Therefore, the minimum total fare is $300 + 220 = 520$ yen.
