C :

#include<stdio.h>
main()
{
	int a,b,c;
	int d=0;
	scanf("%d%d%d",&a,&b,&c);
	d=a+b+c;
	if(d%2==0)
	{
	    if(a+b>=c)
	     {
	        printf("Yes");
	     }
	      else
	     {
	        printf("No");
         }
    }
	else
	printf("Bad");	
}

C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int a,b,c,z;
	cin>>a>>b>>c;
	z=a+b+c;
	if(z%2==0&&a+b>=c)cout<<"Yes"<<endl;
	else if(z%2!=0)cout<<"Bad"<<endl;
	else cout<<"No"<<endl;
	return 0;
}

Java :

import java.util.Scanner;
   public class Main
{
   public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		int a = sc.nextInt();
		int b = sc.nextInt();
		int c = sc.nextInt();
		int x = a+b+c;
		if (x % 2 == 0){
			if (a+b>=c){
		       System.out.println("Yes");
			}else{ 
			   System.out.println("No");
			}
		}else {
		      System.out.println("Bad");
		}
		  
		  
	}
}

Python :

n = input().split()
a = int(n[0])
b = int(n[1])
c = int(n[2])
su = a + b + c
if su % 2 == 0 and a + b >= c:
    print('Yes')
if su % 2 == 0 and a + b < c:
    print('No')
if su % 2 == 1:
    print('Bad')
