本场ABC难度 from AtCoder Problems A - Takoyaki Editorial / Time Limit: 2 sec / Memory Limit: 1024 MB Problem Statement Takahashi loves takoyaki - a ball-shaped snack. With a takoyaki machine, he can make at most $X$ pieces of takoyaki at a time, taking $T$ minutes regardless of the number of pieces to make. How long does it take to make $N$ takoyaki? Constraints $1 \leq N,X,T \leq 1000$ All values in input are integers. Takahashi一次可以做$X$个章鱼烧，需要花费$T$分钟，求出做$N$个章鱼烧Takahashi需要的时间。 我们只需求出Takahashi需要做几次章鱼烧（即$\left(N-1)\right/X+1$次），再将次数$\times T$就好了。 #include <bits/stdc++.h> using namespace std; int n,x,t; int main() { scanf ( "%d%d%d" ,&n,&x,&t); printf ( "%d\n" ,((n-1)/x+1)*t); return 0; } B - Multiple of 9 Editorial / Time Limit: 2 sec / Memory Limit: 1024 MB Problem Statement An integer $N$ is a multiple of $9$ if and only if the sum of the digits in the decimal
