help me mik cần gấp c++ ạ

#include<bits/stdc++.h>
#define ll long long
#define ios ios_base::sync_with_stdio(0);cin.tie(0);cout.tie(0);
#pragma GCC optimize("O3","unroll-loops")
#pragma GCC optimize("Ofast")
using namespace std;

int main() {
    ios
    ll a,b,c;
    cin>>a>>b>>c;
    if(a+b>c&&a+c>b&&b+c>a)
    {
        if(a!=b&&a!=c&&b!=c)
            cout<<"YES";
        else cout<<"NO";
    }
    else
    {
         cout<<"NO";
    }
    return 0;
}

#include<bits/stdc++.h>
using namespace std;
bool tg(long long a,long long b , long long c)
{
    if (a + b > c && a + c > b && b + c > a) {
    if(a!=b && A!=c && b!=c)
        return true;
}
return false;
}
int main()
{
long long a,b,c;
    cin>>a>>b>>c;
    if(tg(a,b,c))
    {
        cout<<"YES";
    }
    else
