Problem Statement

There are three houses on a number line: House 1, 2 and 3, with coordinates A, B and C, respectively.
Print Yes if we pass the coordinate of House 3 on the straight way from House 1 to House 2 without making a detour, and print No otherwise.

Constraints

0\leq A,B,C\leq 100

A, B and C are distinct integers.

Input

Input is given from Standard Input in the following format:

Solution in Ruby (2.3.3) (judge verdict: Wrong Answer)

3.times do |i|
	if i == 0
		N = gets.to_i
	elsif i == 1
		S = gets.to_s.chomp
	elsif i == 2
		K = gets.to_i
	end
end
i = 0
while i < N
	if S[K-1] == S[i]
	else
		S[i] = '*'
	end
	i += 1
end
puts S
