 综上分析，递推代码如下：
 
-```C++
-dp[i][0] = max(dp[i - 1][0], max(dp[i - 1][3], dp[i - 1][1]) - prices[i];
-dp[i][1] = max(dp[i - 1][1], dp[i - 1][3]);
-dp[i][2] = dp[i - 1][0] + prices[i];
-dp[i][3] = dp[i - 1][2];

 ```C++
 dp[i][0] = max(dp[i - 1][0], max(dp[i - 1][3]- prices[i], dp[i - 1][1]) - prices[i];
 dp[i][1] = max(dp[i - 1][1], dp[i - 1][3]);
