New Driver’s License problem

Question

Hello !
So when I compile the code on my computer works fine and the calculations are right. But here I have some problem with the input of the names of the other four customers. Does somebody see the mistake?

import java.util.Scanner;

public class Program {

public static void main(String[] args) {

Scanner in=new Scanner(System.in);
String myName=in.nextLine();
int agents=in.nextInt();
String four=in.nextLine();
String[]names=four.split(" ");
int myPlace=1;
int howLong=0;
for (int i=0; i<names.length; i++) {
if(myName.compareTo(names[i])>0)
myPlace++;
}
if(myPlace==1||names.length+1==agents)
howLong=20;
else
howLong=(Math.round(myPlace/agents))*20;

System.out.println(howLong);
}

}

Answer 1

well, try that, it worked😉:

import java.util.Scanner;
import java.util.ArrayList;
import java.util.Collections;

public class Program
{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String myname = sc.nextLine();
int agent = sc.nextInt();
String dummy = sc.nextLine(); // <-- ??????????????
String others = sc.nextLine();
sc.close();
String[] alt = others.split(" ");
ArrayList<String> names = new ArrayList<String>();
for (int i=0; i<alt.length; i++) {
names.add(alt[i]);
}
names.add(myname);
Collections.sort(names);
int pos = names.indexOf(myname) + 1;
int a = 0;
do {
pos -= agent;
a++;
} while (pos>0);
System.out.println(a*20);
}
}

Answer 2

After inputting the number of agents, add this line:
String dummy = sc.nextLine()

The reason why your code is not working is because after inputting the int, there is a newline character which is not inputted. So storing that in a dummy String will make the program work and the rest of the inputs will work fine.

Answer 3

Then you would have to check the second letter and follow the alphabetical order. If 2nd letter also matches then check the 3rd and so on.

Answer 4

so finally how is the result?????'

Answer 5

that fixed it ! thanks ! 2 tests fail though..i wonder why.. for example if the name of someone else starts with the same letter as yours what would be the case then

Answer 6

it worked. the problem were the number of agents not the names

Answer 7

myname = input()
num_agents = int(input())
other_names = list(input().split())

other_names.append(myname)
other_names.sort()

ind_myname = other_names.index(myname)+1

print('20' if ind_myname <=num_agents else (ind_myname-num_agents)*20+20)
