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`.
