编写一个程序,在屏幕上出现一个圆心沿正弦曲线轨迹移动的实心圆,要求每隔4分之一周期,圆的填充色和圆的周边颜色都发生变化(颜色自己选取),同时圆的半径在四分之一周期内由正弦曲线幅值的0.2倍至0.6倍的线性增长。-The preparation of a procedure on the screen there is a center of a circle along the sinusoid trajectory mobile solid round, one request every 4 cycles, a circle filled with color and circle around the color change (color select their own), while the radius of a circle in the quarter-cycle sinusoid amplitude by 0.2 times to 0.6 times the linear growth.
