Hello. I write program and test it on input example. It works. But when i send it i receive wrong answer at test #1. Please tell me what test fail and tell what need more in program for complete all tests.

#include <iostream>
#include <vector>

#include <string>
#include <stdlib.h>

using namespace std;

int table[256];

string convert(string str) {
    char buf[1];
    string res;
    res.resize(str.length());
    for (int i = 0; i<str.length(); i++) {
        sprintf(buf, "%d", table[str[i]]);
        res[i] = buf[0];
    }
    return res;
}

void fill() {
        table['i'] = table['j'] = 1;
        table['a'] = table['b'] = table['c'] = 2;
        table['d'] = table['e'] = table['f'] = 3;
        table['g'] = table['h'] = 4;
        table['k'] = table['l'] = 5;
        table['m'] = table['n'] = 6;
        table['p'] = table['r'] = table['s'] = 7;
        table['t'] = table['u'] = table['v'] = 8;
        table['w'] = table['x'] = table['y'] = 9;
        table['o'] = table['q'] = table['z'] = 0;
}

int main()
{
    fill();
    string number;
    int numword;
    while(1) {
        cin >> number;
        int z = number.find('-');
        if (z!=-1) break;
        cin >> numword;
        vector<string> dict(numword);
        for (int i = 0; i<numword; i++) {
            cin >> dict[i];
        }
        int pos = 0;
        bool flag = false;
        for (int i = 0; i<numword; i++) {
            if (convert(dict[i]).compare(number.substr(pos, dict[i].length()))==0&&pos+dict[i].length()<=number.length()) {
                cout << dict[i];
                if (pos+dict[i].length()<number.length()) {
                    cout << " ";
                }
                flag = true;

            }
