New Driver’s License problem

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); } }

well, try that, it workedūüėČ: 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); } }

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.

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.

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

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)
