求大佬帮我看看,,第四个点一直WA

#include <bits/stdc++.h>

        r = a % b;
    }
    return b;
}

        cout << "[";

            if(i == 0)
                cout << div;
            else
                if(i == 1)
                    cout << ";" << div;

                swap(fz,fm);
            i++;
        }
        if(fm != 0)
            cout << "," << fm;
        cout << "]" << endl;
    }
    }
