第二步：

进入虚拟的Winxp，工具-》映射网路驱动-》选择VBoxSr\XXX

题目：将array数组中，从begin下标到end下标之间的元素反序一下，如一个数组初始值是[1, 2, 3, 4, 5, 6]，begin为1，end为4，那么当调用了Reverse之后，array数组中的元素便依次成为[1, 5, 4, 3, 2, 6]，其中从array[1]到array[4]之前的元素被反序了

arr =[1,2,3,4,5,6]
def reverse(list,b,e)

while(b<e)
list[b],list[e] = list[e],list[b]
b = b+1
e = e-1
end
list
end

p reverse(arr,1,3)
