Problem Statement

A country decides to build a palace.

In this country, the average temperature of a point at an elevation of x meters is T-x \times 0.006 degrees Celsius.

There are N places proposed for the place. The elevation of Place i is H_i meters.

Among them, Princess Joisino orders you to select the place whose average temperature is the closest to A degrees Celsius, and build the palace there.

Print the index of the place where the palace should be built.

It is guaranteed that the solution is unique.

Constraints

1 \leq N \leq 1000

0 \leq T \leq 50

-60 \leq A \leq T

0 \leq H_i \leq 10^5

All values in input are integers.

The solution is unique.

Input

Input is given from Standard Input in the following format:

N
T A
H_1 H_2 ... H_N

Output

Print the index of the place where the palace should be built.

Sample Input 1

2
12 5
1000 2000

Sample Output 1

1

The average temperature of Place 1 is 12-1000 \times 0.006=6 degrees Celsius.

The average temperature of Place 2 is 12-2000 \times 0.006=0 degrees Celsius.

Thus, the palace should be built at Place 1.

Solution in Scala (2.11.7) (judge verdict: Wrong Answer)

object Main extends App {
    val n:Int = scala.io.StdIn.readLine().toInt
    val Array(t, a) = scala.io.StdIn.readLine().split("\\s").map(_.toInt)
    val h = scala.io.StdIn.readLine().split("\\s").map(_.toInt)

    var diff:Double = Math.pow(10,15)
    var result:Int = 0

    for (i <- 1 to n) {
      val tmp_h = h(i-1)
      val tmp_t = t - tmp_h * 0.006
      val tmp_diff = a - tmp_t
      if (diff > tmp_diff) {
        diff = tmp_diff
        result = i
      }
    }

    println(result)
}
