题目:UVA - 357Let Me Count The Ways(完全背包)
题目大意:给出N,问用1, 5, 10, 25, 50,这些硬币能够凑出N的方式有多少种。
代码:
#include <cstdio>
#include <cstring>
const int N = 5;
const int maxn = 30005;
const int coin[N] = {1, 5, 10, 25, 50};
typedef long long ll;
ll f[maxn];
void init () {
	for(int i = 1; i < maxn; i++)
		f[i] = 0;
	f[0] = 1;
	for (int i = 0; i < N; i++)
		for (int j = coin[i]; j < maxn; j++) {
			f[j] += f[j - coin[i]];
		}
}
int main () {
	int n;
	init();
	while (scanf ("%d", &n) != EOF) {
		if (f[n] == 1)
			printf ("There is only 1 way to produce %d cents change.\n", n);
		else
			printf ("There are %lld ways to produce %d cents change.\n", f[n], n);
	}
	return 0;
}
