[LeetCode]Maximum Product Subarray

  这题如果没有负数和0，答案就很简单了，所有数的乘积。有负数和0就要复杂一些。 先考虑只有正数和负数而没有 0 的情况： 负数是偶数个。答案也很简单，所有数的乘积。 负数是奇数个。那就要枚举这个负数位置，将序列分成两部分，取乘积大的那部分。 然后再考虑数据中有 0 的情况，这时我们可以将整个序列以 0 进行分割成多个子序列，每个子序列

思路：很基础的动态规划题，可以用2个中间变量保存结果，curRet保存包含第i个元素的最大连续和，则计算包含第i+1个元素的最大连续和时，如果curRet<0，则第i+1只需要考虑A[i+1]元素，即更新curRet=A[i+1]，否者，更新curRet=A[i+1]+curRet;中间过程的需要保存一个最大值maxRet=max(maxRet,curRet);code:classSolution
