int main(){
    int t;
    cin>>t;
    while(t--){
        int tmp;
        cin>>tmp;
        v.push_back(tmp);
    }
    int left_side=v[0],now=v[1],right_side=-1,cnt=0;
    for(int i=2;i<v.size();i++){
        right_side=v[i];   
        if(left_side>now && now<right_side){
            cnt++;
            // cout<<"left_side = "<<left_side<<" now  = "<<now<<" right_side = "<<right_side<<endl;
            // cout<<"cnt = "<<cnt<<endl;
        }
