Problem Statement
You are given an integer sequence of length N: $A=(A_1,A_2,\ldots,A_N)$.
You will perform the following consecutive operations just once:
-
Choose an integer $x (0\leq x \leq N)$. If x is 0, do nothing. If x is 1 or greater, replace each of $A_1,A_2,\ldots,A_x$ with L.
-
Choose an integer $y (0\leq y \leq N)$. If y is 0, do nothing. If y is 1 or greater, replace each of $A_{N},A_{N-1},\ldots,A_{N-y+1}$ with R.
Print the minimum possible sum of the elements of A after the operations.
Input
Input is given from Standard Input in the following format:
N L R
$A_1 A_2 \ldots A_N$
Output
Print the answer.
Constraints
- $1 \leq N \leq 2\times 10^5$
- -$10^9 \leq L, R\leq 10^9$
- -$10^9 \leq A_i\leq 10^9$
- All values in input are integers.
Sample Input 1
5 4 3
5 5 0 6 3
Sample Output 1
14
If you choose x=2 and y=2, you will get A = (4,4,0,3,3), for the sum of 14, which is the minimum sum achievable.
Sample Input 2
4 10 10
1 2 3 4
Sample Output 2
10
If you choose x=0 and y=0, you will get A = (1,2,3,4), for the sum of 10, which is the minimum sum achievable.
Sample Input 3
10 -5 -3
9 -6 10 -1 2 10 -1 7 -15 5
Sample Output 3
-58
L, R, and A_i may be negative.
