using namespace std;

string inp;

char a1,a2;

int p,sz,sol;

int main()

{

    ios::sync_with_stdio(0);

    cin.tie(0);cout.tie(0);

    cin>>inp>>p;

    sz=inp.size();

    int h1=0,h2=0;

    while(p--)

    {

        cin>>a1>>a2;

        for(int i=0;i<sz;i++)

        {

            if(inp[i]==a1)h1++;

            else if(inp[i]==a2)h2++;

            else sol+=min(h1,h2),h1=h2=0;

        }

    }

    sol+=min(h1,h2);

    cout<<sol;

    return 0;
