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) {
	// 1行目がinput[0], 2行目がinput[1], …に入る
	input = input.split("\n");
    tmp2 = input[1].split(" ");
    tmp3 = input[2].split(" ");
    T = parseInt(tmp2[0]);
    A = parseInt(tmp2[1]);
    var ans;
    var ansAmari=10000000;
	//文字列から10進数に変換するときはparseIntを使います
    for(i = 1;i <= parseInt(input[0]);i++){
        kion = T - parseInt(tmp3[i]) * 0.006;
        amari = A - kion;
        if(ansAmari > amari){
            ans = i;
            ansAmari = amari;
        }
    }
	console.log('%d',ans);
}
