编写一个一个程序，在屏幕上出现一个圆心沿正弦曲线轨迹移动的实心圆，而且，每隔四分之一周期，圆的填充色和圆的周边颜色都发发生了变化(颜色自己选取)，同时，圆的半径在四分之一周期之内由正弦曲线幅值的0.2倍至0.6倍线性增长。-procedures appeared on the screen in the center of a circle along a sinusoidal curve track the movement of a solid round, but every fourth cycle, a round filled with the color and the color surrounding the yen has made a change (their color selection), while the radius of the circle fourth cycle from within the amplitude of the sine curve of 0.2 times to 0.6 times the linear growth.
