二路归并排序的基本思想：设 n 个待排记录，看成是 n 个有序的子序列，每个子序列的长度为 1 ，对此进行两两归并，得到 n/2 个长度为 2 或 1 的有序子序列；再继续两两归并，得到 n/4 个有序子序列，重复进行直至得到一个长度为 n 的有序序列为止。
public class MergeSort {
public static void main(String[] args) {
//int[] arr = { 9, 8, 7, 6, 5, 4, 3, 2, 1 };

1、定义一个canvas。
<view>
<canvas canvas-id=”miCanvas”></canvas>
</view>
2、js生成过程。
const ctx = wx.createCanvasContext(‘miCanvas’)
//1、先绘制一个完整的白色实体圆
ctx.arc(100, 75, 50, 0, 2 * Math.PI);
ctx.setFillStyle(‘#FFFFFF’
