    unsigned long long x = 1, y = 1, z = 0;
    printf("db[5007] = {");
    for (int i = 0; i < 5000; i++)
    {
        z = x + y;
        x = y;
        y = z;
        if (i == 4999)
        {
        	printf("%lld};");
		}
        else
		{
			printf("%lld, ", x);
		}
    }
    return 0;
}

哪位dalao帮蒟蒻合并一下两段代码吧QwQ
