if condition is getting skipped when condition is false

I am trying to solve a problem and i am pretty sure the code works. However it turns out that when passing by this part

                    int x = it->second;
                    if ( x > max);
                    {
                        f = it->first;
                        max = it->second;
                    }

it skips immediately to the if block without checking the condition , some help please?

here is the full code

            #include<iostream>
            #include<algorithm>
            #include<vector>
            #include<map>
            #include<set>
            #include<string>
            #include<queue>

            using namespace std;

            int main(){
                int n;
                cin >> n;
                map<string, int> m;
                string s;
                for (int i = 0; i < n; i++)
                {
                    cin >> s;
                    m[s]++;
                }
                string f;
                int max = -1;
                map<string,int>::iterator it;
                for (it=m.begin(); it!=m.end(); it++)
                {
                    int x = it->second;
                    if ( x > max);
                    {
                        f = it->first;
                        max = it->second;
                    }
                }
                cout << f << endl;
                return 0;
            }
