使用分治思想 求数组中的最大和最小值

        System.out.println("最小值:"+minMax.getMin());
        System.out.println("最大值:"+minMax.getMax());
        
    }
    
    public static MinMax getMinMax(int [] array,int start,int end){
        
        //分治的终止条件 如果  两个坐标相邻 或者是同一个坐标，返回最小的值和最大的值
        if(end-start<=1){
            if(array[start]>array[end]){
                return new MinMax(array[end],array[start]);
            }else

            }
        }
        else{
            
            //如果开始下标和终止下标没有到达终止下标，求出中间坐标
            int mid = (start+end)/2;
            MinMax left = getMinMax(array, start, mid);
            MinMax right = getMinMax(array, mid+1, end);
