C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int a,b,c;
	cin>>a>>b>>c;
	if(a>=90&&b>=90&&c>=90)cout<<"Yes"<<endl;
	else cout<<"No"<<endl;
	return 0;
}

Python :

# coding=utf-8
a = int(input())
b = int(input())
c = int(input())

if(a>=90 and b>=90 and c>=90):
    print('Yes')
else:
    print('No')
