# 478. Generate Random Point in a Circle LeetCode Solution Share:

Generate Random Point in a Circle 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`.
