Description
给定圆的半径和圆心的位置，实现函数
randPoint ，在圆中产生均匀随机点。实现
Solution 类:Solution(double radius, double x_center, double y_center) 用圆的半径 radius 和圆心的位置 (x_center, y_center) 初始化对象randPoint() 返回圆内的一个随机点。圆周上的一点被认为在圆内。答案作为数组返回 [x, y] 。Example
输入:
["Solution","randPoint","randPoint","randPoint"]
[[1.0, 0.0, 0.0], [], [], []]
输出: [null, [-0.02493, -0.38077], [0.82314, 0.38945], [0.36572, 0.17248]]
解释:
Solution solution = new Solution(1.0, 0.0, 0.0);
solution.randPoint ();//返回[-0.02493，-0.38077]
solution.randPoint ();//返回[0.82314,0.38945]
solution.randPoint ();//返回[0.36572,0.17248]
