public class Solution extends Object
478 - Generate Random Point in a Circle\. Medium Given the radius and the position of the center of a circle, implement the function `randPoint` which generates a uniform random point inside the circle. Implement the `Solution` class: * `Solution(double radius, double x_center, double y_center)` initializes the object with the radius of the circle `radius` and the position of the center `(x_center, y_center)`. * `randPoint()` returns a random point inside the circle. A point on the circumference of the circle is considered to be in the circle. The answer is returned as an array `[x, y]`. **Example 1:** **Input** ["Solution", "randPoint", "randPoint", "randPoint"] [[1.0, 0.0, 0.0], [], [], []] **Output:** [null, [-0.02493, -0.38077], [0.82314, 0.38945], [0.36572, 0.17248]] **Explanation:** Solution solution = new Solution(1.0, 0.0, 0.0); solution.randPoint(); // return [-0.02493, -0.38077] solution.randPoint(); // return [0.82314, 0.38945] solution.randPoint(); // return [0.36572, 0.17248] **Constraints:** * 0 < radius <= 108 * -107 <= x_center, y_center <= 107 * At most 3 * 104 calls will be made to `randPoint`.
