If you have figured out the O(n) solution, try coding another solution using the divide and conquer approach, which is more subtle.
解题思路：最大子序列和问题，直接上代码，不是我能想出来的。
代码：
class Solution: # @param A, a list of integers # @return an integer def maxSubArray(self, A): ThisSum = 0 MaxSum = -10000 for i in range( 0, len(A) ): if ThisSum < 0: ThisSum = 0 ThisSum = ThisSum + A[ i ] MaxSum = max( ThisSum, MaxSum ) return MaxSum
