迷のbug

　　已解决（ps over%100写错了，应该是over/100。。。）

#include <bits/stdc++.h>
#define rep(i, a, b) for(int i = a; i < b; i++)
int gcd(int a, int b){return b == 0 ? a : gcd(a%b, a);}
const int N = 12;
int main()
{
	int m, over = 0, re; double save = 0.;
	for(int i = 0; scanf("%d", &m) and i < N; i++)
	{
		over += 300 - m;
		if (over > 99) re = (over % 100) * 100, save += re, over -= re;
		else if (over < 0) return printf("-%d
", i + 1), 0;
	}
	save *= 1.2;
	return printf("%d
", over + (int)save), 0;
}

　　解决了（ps 因为我的m设置得还是太小了，改为0x3f3f3f3f就过了）：

#include <bits/stdc++.h>
#define rep(i, a, b) for(int i = a; i < b; i++)
#define min(a, b) ((a) < (b) ? (a) : (b))
int gcd(int a, int b){return b == 0 ? a : gcd(a%b, a);}
const int N = 3;
int main()
{
	int a, b, c, k, m = 100010;
	scanf("%d", &a);
	for(int i = 0; scanf("%d %d", &b, &c) && i < N; i++)
	{
		k = (int)ceil((double)a / (double)b);
		m = min(m, k*c);
	}
	return printf("%d
", m), 0;
}
