weekly contest 121

Jan. 31, 2019

Introduction


I chose to go to Chinese party in the city of Surrey, so I did not play the contest. But my ranking is 2173/ 3924. So many people did not play the contest or could not score.

Catch up 


The contest was hold on Jan. 26, last Saturday 8:00 PM. Today is Thursday, I found time to work on the contest, and I felt that the algorithms are so tough to work on. I have not written any code last week, it is so challenging for me to work on algorithm now.


984. String Without AAA or BBB
