Print a point chosen uniformly at random inside the circle of radius 1 centered at (a, b).
One line contains three integers n (0 < n ≤ 1000), a and b (-100 ≤ a, b ≤ 100).
Print n lines. Each line must contain two real numbers x and y, where (x, y) is a uniformly chosen point strictly inside the circle of radius 1 centered at (a, b).
