不知道为什么，提交时一直显示这个：

Argument 1 passed to Luogu\Library\Document\DoubleLayerEncryptionHelper::__construct() must be of the type string, null given, called in /app/source/src/Library/Judge/Judger/RemoteJudgeJudger.php on line 118

这是代码：

#include<bits/stdc++.h>

using namespace std;
int n,m,t,v,ans,dp[100001];
int main()
{
    cin >> n;
    for(int i=1;i<=n;i++)
	{
        memset(dp,0x8f,sizeof(dp));
        cin >> m >> t;
        dp[0]=0;
        for(int j=1;j<=m;j++)
        {
            cin >> v;
            for(int k=t-1;k>=v;k--)
                 dp[k]=max(dp[k],dp[k-v]+1);
        }
        for(int j=ans=t-1;j>=0;j--)
            if(dp[j]>dp[ans]) ans=j;
        printf("Case %d: %d %d\n",i,dp[ans]+1,ans+678);
    }
    return 0;
}
