Problem Statement

"Pizza At", a fast food chain, offers three kinds of pizza: "A-pizza", "B-pizza" and "AB-pizza". A-pizza and B-pizza are completely different pizzas, and AB-pizza is one half of A-pizza and one half of B-pizza combined together. The prices of one A-pizza, B-pizza and AB-pizza are A yen, B yen and C yen (yen is the currency of Japan), respectively.

Nakahashi needs to prepare X A-pizzas and Y B-pizzas for a party tonight. He can only obtain these pizzas by directly buying A-pizzas and B-pizzas, or buying two AB-pizzas and then rearrange them into one A-pizza and one B-pizza. At least how much money does he need for this? It is fine to have more pizzas than necessary by rearranging pizzas.

Constraints

1 ≤ A, B, C ≤ 5000

1 ≤ X, Y ≤ 10^5

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A B C X Y

Output

Print the minimum amount of money required to prepare X A-pizzas and Y B-pizzas.

Sample Input 1

1500 2000 1600 3 2

Sample Output 1

7900

It is optimal to buy four AB-pizzas and rearrange them into two A-pizzas and two B-pizzas, then buy additional one A-pizza.

Sample Input 2

1500 2000 1900 3 2

Sample Output 2

8500

It is optimal to directly buy three A-pizzas and two B-pizzas.

Sample Input 3

1500 2000 500 90000 100000

Sample Output 3

100000000

It is optimal to buy 200000 AB-pizzas and rearrange them into 100000 A-pizzas and 100000 B-pizzas. We will have 10000 more A-pizzas than necessary, but that is fine.

Solution in JavaScript (node.js v5.12) (judge verdict: Wrong Answer)

function Main(input) {
  	var A = parseInt(input.split(" ")[0]);
  var B = parseInt(input.split(" ")[1]);
  var C = parseInt(input.split(" ")[2]);
  var X = parseInt(input.split(" ")[3]);
  var Y = parseInt(input.split(" ")[4]);
  
  var getABcount = Math.min(X,Y) * 2;
  if(Math.min(A,B) < C){
  if(X > Y){
     console.log(Math.min((X - Y) * A + C * getABcount,A * X + B * Y));
  }else if(Y > X){
     console.log(Math.min((Y - X) * B + C * getABcount,A * X + B * Y));
  }else{
     console.log(Math.min(C * getABcount,A * X + B * Y));
  }
  }else{
    console.log(C * Math.max(X,Y) * 2);
  }
}
