Problem Statement

A country decides to build a palace.

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

There are NN places proposed for the place. The elevation of Place ii is HiH_i meters.

Among them, Princess Joisino orders you to select the place whose average temperature is the closest to AA 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

  • 1N10001 \leq N \leq 1000
  • 0T500 \leq T \leq 50
  • 60AT-60 \leq A \leq T
  • 0Hi1050 \leq H_i \leq 10^5
  • All values in input are integers.
  • The solution is unique.

  • The average temperature of Place 11 is 121000×0.006=612-1000 \times 0.006=6 degrees Celsius.
  • The average temperature of Place 22 is 122000×0.006=012-2000 \times 0.006=0 degrees Celsius.

Thus, the palace should be built at Place 11.
