我的搜索顺序是对的，剪枝也是对的，就是不过
我的算法和那些通过了的差不多，怎么我的就是不过了，能帮我看一下我的程序吗？
非常谢了!
#include <iostream.h>
int a[100], b[100];
int flag;
int length, n, sticks;
void search(int num, int now, int next);
void solve(int num)
{
	if (num>sticks) {flag = 1; cout<<length<<endl; return;}
	int i;
	for (i=1; i<=n; i++) if (!b[i]) break;
	b[i] = 1;
	search(num, a[i], i);
	b[i] = 0;
}

void search(int num, int now, int next)
{
	if (flag == 1) return;
	if (now == length) { solve(num+1); return;}
	if (next+1 > n) return;
