And can anybody tell me what is the upper bound of the number n,t and m?

This is my code:
/* @JUDGE_ID: 18814EA G C++ */

#include <iostream>
#include <string>
#include <sstream>
#include <iomanip>
#include <vector>

using namespace std;

struct Oper
{
long op;
long pri;
};

std::vector<double> number;
std::vector<Oper> operators;

double solve(istream &sin)
{
double ...

I've tried many I/O's but still got WA and don't know why.
It the case like ---9 vaild in this problem?

Can someone give me some I/O's?

I don't know why... here is my code
#include <stdio.h>

int print(char character, int num)
{
int i;
for (i = 0 ; i < num ; i++)
{
printf("%c",character);
}
return 0;
}

int main()
{
char input;
char ouput;
int num;
bool lined;
num = 0;
lined = false;
while ((input = getchar()) != EOF ...

I solve this problem using Ad Hoc algorithm and got 1.041 second, I feel there is a faster algorithm to solve it. But I don't know, is there any faster algorithm to solve the problem?
