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

function Main(input){
var N = input.split("\n")[0];
var T = input.split("\n")[1].split(" ")[0];
var A = input.split("\n")[1].split(" ")[1];
var H = input.split("\n")[2].split(" ");
var a = [];
var min;
for(i=0;i<=(N-1);i++){
  var temp_hi = parseInt(T,10) - parseInt(H[i],10)*0.006;
  if(parseInt(A,10)>=0){
    var x = temp_hi - parseInt(A,10);
  }else{
    var x = temp_hi + parseInt(A,10);
  }
  a[i] = Math.abs(x);
  if(i>=1&& a[i-1]>a[i]){
    min = i+1;
  }else if(i>=1&& a[i]>=a[i-1]){
    min = i;
  }
}
console.log(min);
}
