И да код я делал чтоб например 57 превращалось в 2 и тд,
package com.javarush.task.task04.task0416;
import java.io.BufferedReader;
import java.io.InputStreamReader;
/*
Переходим дорогу вслепую
*/
public class Solution {
public static void main(String[] args) throws Exception {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String st = reader.readLine();
double t = Double.parseDouble(st);
double a = t/5;
int b;
if (a<=1 & a>=0)
b = 1;
else if (a<=2 & a>1)
b = 2;
else if (a<=3 & a>2)
b = 3;
else if (a<=4 & a>3)
b = 4;
else if (a<=5 & a>4)
b = 5;
else if (a<=6 & a>5)
b = 6;
else if (a<=7 & a>6)
b = 7;
else if (a<=8 & a>7)
b = 8;
else if (a<=9 & a>8)
b = 9;
else if (a<=10 & a>9)
b = 10;
else if (a<=11 & a>10)
b = 11;
else if (a<=12 & a>11)
b = 12;
int c = b*5;
double d = t - c;
}
