小A 和 小B 在玩猜数字。小B 每次从 1, 2, 3 中随机选择一个，小A 每次也从 1, 2, 3 中选择一个猜。他们一共进行三次这个游戏，请返回 小A 猜对了几次？

\n\n

输入的guess数组为 小A 每次的猜测，answer数组为 小B 每次的选择。guess和answer的长度都等于3。

\n\n

示例 1：

\n\n
\n输入：guess = [1,2,3], answer = [1,2,3]\n输出：3\n解释：小A 每次都猜对了。
\n\n

示例 2：

\n\n
\n输入：guess = [2,2,3], answer = [3,2,1]\n输出：1\n解释：小A 只猜对了第二次。
