#define all(v) (v).begin(), (v).end()
#define sz(v) (int)(v).size()
#define ll long long
#define N 123451

int vis[10];

int main(){
        int a, b, c;
        cin >> a>> b>> c;
        vis[a]++;
        vis[b]++;
        vis[c]++;
        if (vis[5] == 2 && vis[7] == 1)
                cout << "YES\n";
        else 
                cout << "NO\n";
