论我的一篇代码在 Dev-C++ 上没问题，但在洛谷上有问题（ \text\color{7f00FF}{Runtime Error} ）这件事

代码：

#include<bits/stdc++.h>
using namespace std;
#define maxNum 25
int n;
int __time__[5];
int qtm;
int var[26];
int p[maxNum];
vector<string> prg[maxNum];
deque<int> readyQ;
queue<int> blockQ;
bool locked;
string s;
const char assign = '=', output = 'i', _lock = 'c', unlock = 'l', _end = 'd';

void execute(int i)
{
	int t = qtm, v = 0;
	while(t)
	{
		string cur;
		cur = prg[i][p[i]];
		switch (cur[2])
		{
			case assign:
			{
				t -= __time__[0];
				v = cur[4] - '0';
				if(cur.size() == 6)
				{
					v = v * 10 + cur[5] - '0';
				}
				var[cur[0] - 'a'] = v;
				break;
			}
			case output:
			{
				t -= __time__[1];
				printf("%d: %d\n", i, var[cur[6]-'a']);
				break;
			}
			case _lock:
			{
				t -= __time__[2];
				if(locked)
				{
					blockQ.push(i);
					return;
				}
				else
				{
					locked = 1;
				}
				break;
			}
			case unlock:
			{
				t -= __time__[3];
				locked = 0;
				if(!blockQ.empty())
				{
					int u = blockQ.front();
					blockQ.pop();
					readyQ.push_front(u);
				}
				break;
			}
			case _end:
			{
				return;
				break;
			}
		}
		p[i]++;
	}
	readyQ.push_back(i);
}

int main()
{
	int T;
	cin >> T;
	while(T--)
	{
		cin >> n;
		for(int i=0;i<5;i++)
		{
			cin >> __time__[i];
		}
		cin >> qtm;
		memset(var, 0, sizeof(var));
		for(int i=1;i<=n;i++)
		{
			prg[i].clear();
			while(getline(cin, s))
			{
				prg[i].push_back(s);
				if(prg[i].back() == "end")
				{
					break;
				}
			}
			readyQ.push_back(i);
		}
		memset(p, 0, sizeof(p));
		memset(var, 0, sizeof(var));
		locked = 0;
		while(!readyQ.empty())
		{
			int pid = readyQ.front();
			readyQ.pop_front();
			execute(pid);
		}
		if(T)
		{
			cout << endl;
		}
	}
	return 0;
}

输入：

1

3 1 1 1 1 1 1
a = 4
print a
lock
b = 9
print b
unlock
print b
end
a = 3
print a
lock
b = 8
print b
unlock
print b
end
b = 5
a = 17
print a
print b
lock
b = 21
print b
unlock
print b
end

理想输出：

1: 3
2: 3
3: 17
3: 9
1: 9
1: 9
2: 8
2: 8
3: 21
3: 21
