链接 去年南京邀请赛的水题,当时找规律过的,看它长得很像数位dp,试了试用数位dp能不能过,d出每位上有多少个1,然后TLE了..然后用规律优化了前4位,勉强过了. 附数位dp代码及找规律代码. #include <iostream> #include<cstdio> #include<cstring> #include<algorithm> #include<queue> #include<stack> #include<cm…

Carries Problem's Link Mean: 给你n个数,让你计算这n个数两两组合相加的和进位的次数. analyse: 脑洞题. 首先要知道:对于两个数的第k位相加会进位的条件是:a%(10^k)+b%(10^k)>=10^k. 想到这一点后就简单了,枚举每一位(最长9位),然后每个数都模10^k,然后排序二分. 排序后,如果b[i]+b[j]>=k,那么i~j-1这段也满足b[i]+b[j]>=k. Time complexity: O(n*logn) view code…

Description One day, Implus gets interested in binary addition and binary carry. He will transfer all decimal digits to binary digits to make the addition. Not as clever as Gauss, to make the addition from a to b, he will add them one by one from a t…
