有一个数组
lists[]
>>>
['0', '2', '2', '8']
['0', '9', '6', '1']
['3', '9', '6', '1']
['2', '8', '4', '8']
['1', '7', '8', '4']
['8', '0', '2', '8']
['4', '4', '8', '4']
['6', '2', '1', '8']
['9', '6', '6', '9']
['6', '0', '1', '2']
['1', '4', '4', '0']
['1', '7', '4', '6']
['4', '2', '8', '2']
['8', '6', '3', '5']
['4', '9', '2', '7']
['5', '4', '6', '0']
['9', '0', '0', '8']
['6', '3', '6', '2']
['2', '5', '1', '8']
['1', '7', '8', '5']
>>>
要变成这样,
定义n为行数.n-1,n-2,n-3行的数据变成一成的数据如上面第1到第三行的数据['0', '2', '2', '8']['0', '9', '6', '1']['3', '9', '6', '1']
变成[0,2,3,6,8,9,1]
在加入第四行['2', '8', '4', '8']
这样又变成这样的新的数据形式了。
['0','2','3','6','7','8','9'] ['2', '8', '4', '8']
这里是第2行到第四行的数据
['0', '9', '6', '1']
['3', '9', '6', '1']
['2', '8', '4', '8']
['0','9','6','1','3','2','8','4'] ['1', '7', '8', '4']
这个就是我要的数据
['0','2','3','6','7','8','9'] ['2', '8', '4', '8']
['0','9','6','1','3','2','8','4'] ['1', '7', '8', '4']
