     long long n;
      cin>>n;
       long long a[n];
       for(int i=0;i<n;i++)cin>>a[i];
       
     
      long long c=0;
      for(int i=1;i<n-1;i++){
          if(a[i]==a[i-1] and a[i]==a[i+1])c++;;

      }
      if(a[0]==a[1])c++;
      if(a[n-1]==a[n-2])c++;
     // cout<<c<<endl;
      cout<<n<<endl;
