本人的AC代码无法通过样例，却通过了原题？求助

#include<bits/stdc++.h>
using namespace std;
int T;
int main()
{
	scanf("%d",&T);
	while(T--)
	{
		int nm[29]={0},g[29]={0},lp[114]={0};
		string s1,s2;
		int a;string tm;
		cin>>a>>tm;
		int inde=0;int loopn=0,k=0,loopnow=0,n=0,m=0;
		for(int i=4;i<tm.size();i++)if(isdigit(tm[i]))inde=(inde<<3)+(inde<<1)+tm[i]-'0';
        int fl=1;//printf("%d ",inde);
		while(a)
		{
			a--;
			cin>>s1;
			if(s1=="F")
			{
				++loopn;cin>>s1;
				if(nm[s1[0]-'a'+1])loopn=-1;
				nm[s1[0]-'a'+1]=1;g[loopn]=s1[0]-'a'+1;
				cin>>s1>>s2;
				if(s1!="n"&&s2=="n"&&!k)loopnow++,lp[loopn]=1;
				else if(((s1.size()==s2.size()&&s1>s2)||(s1.size()>s2.size())||(s1[0]=='n'&&s2[0]!='n'))&&!k)k=1,n=loopn;
                m=max(m,loopnow);
			}
			else
			{
				m=max(m,loopnow);nm[g[loopn]]=0;
                if(lp[loopn]==1)loopnow--,lp[loopn]=0;
                loopn--;
                if(n>0&&loopn<n)k=0,n=0;
			}
			if(loopn==-1)fl=0;
		}
		if(loopn!=0||!fl)printf("ERR\n");
		else
		{
			if(m==inde)printf("Yes\n");
			else printf("No\n");
		}
	}
}

对于样例的第8个数据，我的代码会return 3221225477，但是可以通过原题，求条
