阿里-暑期实习生蚂蚁笔试题

1的个数

16进制，转成二进制后，1的个数

输入

0x6f

输出

6

比较暴力的一种做法

1 dict1 = {'0':0, '1':1, '2':1,'3':2,'4':1,'5':2, '6':2,'7':3,'8':1,'9':2,
2     'a':2, 'b':3, 'c':2, 'd':3, 'e':3, 'f':4}
3 
4 if __name__=="__main__":
5     str1 = input().strip()
6     ans = 0
7     for i in str1[2:]:
8         ans +=dict1[i]
9     print(ans)

 

消消乐游戏

8*8棋盘，每个棋盘的颜色∈[r,g,b]，每次选一个位置(x,y)，与（x,y) 相同颜色会被消除，消除后，有填充op操作，分别为w，a，s，b代表up，left，down，right。

填充的内容是后台固定的（充钱才能过的游戏都是耍流氓）。up和down填补顺序是第一列，第二列等；left和right填补是第一行，第二行等。她想知道每次操作后消除多少个方格。

输入n，表示操作次数；接下来8行代表初始棋盘，后面8行(长为8*n)代表待填补字符串。

大概思路是这样，样例过了，对不对就不知道了，笔试结束后写的，做个纪念吧
