PixelCompetition/C180

This Competition implement a riddle protocol asking for square roots.
ASK {x} {y}
--> RIDDLE {x} {y} {riddle}

PX {x} {y} #{color} {result}
--> OK
--> Nope --> RIDDLE {x} {y} {riddle}

x:     x-Coordinate of a pixel
y:     y-Coordinate of a pixel
color: color encoded as a html color (rgb-values as hex)

ASK returns a {riddle} for the given coordinate, in this competition it returns a number.
PX  sets a pixel by providing the {result} of the riddle.

{result} shall be the square root of {riddle}

NOTE: Others may solve the riddle faster than you, in this case you get back a nope and the current riddle
