最难的在于我看不懂题
简直哭了
水神翻译之后大概明白
用数组表示一个数 将这个数+1 在存成数组
例如 9327存成[9,3,2,7]
很简单 list→str→long→加一→str→list（使用append或者list相加都行）
代码如下
其实也可以判断最后一位 加一 有无进位 有再往前判断
觉得好像比较麻烦

class Solution: # @param digits, an integer[] # @return an integer[] def plusOne(self, digits): numString='' for i in digits: numString=numString+str(i) numString=str(long(numString)+1) array=[] for j in numString: array=array+[int(j)] return array
