ABSYS problem on spoj

I stuck at a problem SPOJ.com - Problem ABSYS[^]

I executed my program on all the test cases ,I am getting correct answer.

But still I am getting as "wrong answer" on spoj

What I have tried:

Breaking stream into strings storing them into vectors ,so we can say that our vector will have 5 strings (numstring,+,numstring,=,numstring) and then we will inspect each string whenever we found m in the string ,we get to know that string at this position is variable that need to be calculated with the help of other digits strings

And we are also certain about that string with digits can only be at 0,2,4 indices in the vectors other two indices will have + and =


Test cases:

Input:

3

23 + 47 = machula

3247 + 5machula2 = 3749

machula13 + 75425 = 77038
Output:

23 + 47 = 70

3247 + 502 = 3749

1613 + 75425 = 77038

What I have tried:

#include<iostream>
#include<sstream>
#include<vector>
#include<string>
using namespace std;
int main() {
    int t;
    (cin >> t).get();
    while (t--) {
        string str;

        getline(cin, str);
        stringstream split(str);
        string each;
        vector <string> tokens;
        while (getline(split, each, ' ')) {
            ///scan each part of stream;
            tokens.push_back(each);

        }
        int ind = -1;
        for (int i = 0; i < tokens.size(); i++) {
            string temp;
            temp = tokens[i];
            for (int j = 0; j < temp.length(); j++) {
                if (temp[j] == 'm') {
                    ind = i;
                    break;
                }

            }
            if (ind != -1)
                break;
        }
        int i1, i2;
        string str1;
        if (ind == 0) {
            i1 = stoi(tokens[2]);
            i2 = stoi(tokens[4]);
            int result = i2 - i1;
            cout << result << " + " << i1 << " = " << i2 << "\n";
            //break;
        }
        else if (ind == 2) {
            i1 = stoi(tokens[0]);
            i2 = stoi(tokens[4]);
            int result;
            result = i2 - i1;
            cout << i1 << " + " << result << " = " << i2 << "\n";
            //break;
        }
        else if (ind == 4) {
            i1 = stoi(tokens[0]);
            i2 = stoi(tokens[2]);
            int result = i1 + i2;
            cout << i1 << " + " << i2 << " = " << result << "\n";
            //break;
        }
        tokens.clear();
        str.erase();
    }
