Brazil and Germany
By Alexandre Davis, UFMG 
Brazil
Timelimit: 1
Brazil and Germany was a unforgettable match. In this match, Germany scored 7 times in 90 minutes, while Brazil scored only 1. It was an incredible milestone in history of brazilian soccer, so Leonardo decide make a web page for brazilians never forget this splendid day.
The page shows the scoreboard of the match if it was still going on since that fateful July 8, 2014, considering the same rate of scores (like in figure below). Therefore, Leonardo ask for your help to calculate the scoreboard of the match showed on his web page.
Observations
As the web site want shock his fans, the Germany scores should round up while Brazil scores should round down.
Input
The input is composed for one number N (90 ≤ N ≤ 109) indicating how many minutes passed since the start of the match. It ends when N = 0.
Output
The output should write in only one line: “Brasil B x Alemanha A” where B and A are integers indicating how many goals Germany and Brazil did, respectively.
| Input Sample | Output Sample |

Brasil 1 x Alemanha 7 |
Code Examples
#1 Code Example with C++ Programming
Code -
C++ Programming
#include <stdio.h>
#include <stdbool.h>
#include <math.h>
int main (void)
{
double minutos, feitosBrasil, feitosAlemanha;
while (true)
{
scanf("%lf", &minutos);
if (minutos == 0)
break;
feitosBrasil = floor(minutos / 90);
feitosAlemanha = ceil(7 * minutos / 90);
printf("Brasil %.lf x Alemanha %.lf\n", feitosBrasil, feitosAlemanha);
}
}
Input
100
180
0
Output
Brasil 1 x Alemanha 8
Brasil 2 x Alemanha 14
#2 Code Example with Python Programming
Code -
Python Programming
from math import floor as chao
from math import ceil as cezin
while True:
x=int(input())
if x==0:break
brasa=chao(x/90)
alema=cezin(7*x/90)
print(f"Brasil {brasa} x Alemanha {alema}")
Input
100
180
0
Output
Brasil 1 x Alemanha 8
Brasil 2 x Alemanha 14
#3 Code Example with Javascript Programming
Code -
Javascript Programming
const { readFileSync } = require("fs")
const input = readFileSync("/dev/stdin", "utf8").split("\n")
function BrazilVSGermanyBoardFromTime(time = 90) {
const Brazil = Math.floor((time / 90) * 1)
const Germany = Math.ceil((time / 90) * 7)
return [Brazil, Germany]
}
function main() {
const responses = []
for (const time of input) {
if (time == "0") break
const [BRGols, DEGols] = BrazilVSGermanyBoardFromTime(Number.parseInt(time, 10))
responses.push(`Brasil ${BRGols} x Alemanha ${DEGols}`)
}
console.log(responses.join("\n"))
}
main()
Input
100
180
0
Output
Brasil 1 x Alemanha 8
Brasil 2 x Alemanha 14
