• [tab]
• C++

• #include <bits/stdc++.h>
  using namespace std;
  int main(){
      int n;
      cin >> n;
      int a,b,c;
      int s=0;
      for (int i=0;i<n;i++){
          cin >> a >> b >> c;
          if (a+b+c>=2){
              s += 1;}
      }
      cout << s;
      }

• Python 3

• n = int(input())
  cou = 0
  for i in range(n):
      a, b, c = map(int, input().split(' '))
      if a + b + c >= 2:
          cou += 1
  print(cou)
