Problem: Given a real number y   [0,1], find the value of x, in radians, such that sin(x) = y, without using any trigonometric-inverse function. The value x should lie within the interval [0, pi(3.14) /2]. Write an iterative program that prints the value of x. Do NOT use a brute-force search at all.

Constraints

0 <= y <= 1

0 <= x <=  pi (3.14) /2
