C :

#include<stdio.h>
int main()
{
    int x,y;
    scanf("%d%d",&x,&y);
    if(x+y<10)
        printf("water");
if(x+y>10&&x>y)
   
    printf("tree");
    if(x+y>=10&&x<=y)
        printf("tea");
   
    return 0;
}

C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int a,b,z;
	cin>>a>>b;
	z=a+b;
	if(z<10)cout<<"water"<<endl;
	else if(z>=10&&a>b)cout<<"tree"<<endl;
	else cout<<"tea"<<endl;
	return 0;
}

Java :

import java.util.Scanner;
public class Main
{   
	public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        int x = sc.nextInt();
		int y = sc.nextInt();
		int a = x+y;
		if(a<10) {
			System.out.println("water");
		}else if(a>10 && x>y){
			System.out.println("tree");
		}else{
			System.out.println("tea");
		}
		
		
    }
}

Python :

n =input().split()
a=int(n[0])
b=int(n[1])
c=a+b
if c>=10:
    if a>b:
        print('tree')
    else:
        print('tea')
else:
    print('water')
