C. Vlad and a Sum of Sum of Digits 分析 在给定的数据规模下,可以直接暴力计算出每个数的数位之和,求出前缀和后就可以在O(1)的时间复杂度下返回答案,因为数位拆分的时间复杂度为O(nlogn),所以总的时间复杂度为O(nlogn+t),其中t为查询次数。
CodeForces 489C (贪心) Given Length and Sum of Digits...,题意:找出m位且各个数位数字之和为s的最大和最小整数,不包括前导0(比如说003是非法的),但0是可以的。分析:这题是用贪心来做的,同样是m位数,前面的数字越大这个数就越大。所以写一个can(intm,ints)函数,来
