I'm afraid I don't understand this question, but see if the comments below help.

If 0 money is given (as with laura in the sample), that 0 is divided by the number of people to give gifts to, and that result is added to the "net worth" of those people. Just as with any other amount. If you carefully analyze the first sample from the problem statement, you can clearly see what is the result of laura giving away 0 to two friends.

I think the problem statement is failry clear, so when in doubt, take the time to patiently read it as many times as necessary until you understand all the details.

Post in existing thread. Use search by problem number (119). Don't read from file or post here code that you actually submit. Problem description says
The output for each group should be separated from other groups by a blank line
Don't print blank line after last case

Hi I am getting wrong answer from the following code and not able to trace error.Could you help me ?

Code: Select all

import java.util.Scanner;
import java.util.HashMap;

class Main{
public static void main(String[] args) 
	{
        Scanner sc = new Scanner(System.in);       
        while (true) {
        	int n = 0;
            try {
             n = sc.nextInt();
            } catch (Exception e) {
                break;
            }
           String[] friends =new String[n];
           HashMap<String,Integer> map=new HashMap<String,Integer>();
           for(int i=0;i<n;i++)
           {
        	friends[i]=sc.next();
        	map.put(friends[i], i);            
           }
           int []money=new int[n];
            for(int i=0;i<n;i++)
            {
            	int idx = map.get(sc.next());
                int gift = sc.nextInt();
                int M = sc.nextInt();
                if (M!= 0) {               
                int rem =gift%M;
                int dev=gift/M;
                money[idx]+=rem-gift;
                for(int j=0;j<M;j++)
                {
                  money[map.get(sc.next())]+=dev;
                }
                }
            }

Read the problem statement carefully.
The output for each group should be separated from other groups by a blank line.

Please tell me why this code is getting WA?

Code: Select all

#include <stdio.h>
#include <string.h>
 
int main ()
{
    long np, i, money, person, divide, c, flag = 0;
    char giver [20], receiver [20];
 
    while (scanf ("%ld", &np) != EOF) {
 
        struct friends {
            int spend;
            int receive;
            char name [20];
        } A [12] = {0, 0, 0};
 
        for (i = 0; i < np; i++)
        scanf ("%s", A [i].name);
 
        for (c = 0; c < np; c++ ) {
 
            scanf ("%s", giver);
            scanf ("%ld", &money);
 
            i = 0;
            while (strcmp (A [i].name, giver) != 0)
                i++;
            A [i].spend += money;
 
            scanf ("%ld", &person);
            if (person == 0) {
                A [i].receive += money;
                continue;
            }
 
            divide = person;
            A [i].receive += money - ((money / person) * person);
            while (person--) {
                scanf ("%s", receiver);
                i = 0;
                while (strcmp (A [i].name, receiver) != 0)
                    i++;
                A [i].receive += (money / divide);
            }
        }
 
        if (flag == 1)
            printf("\n");
        flag = 1;
 
        for (i = 0; i < np; i++)
            printf("%s %ld\n", A [i].name, A [i].receive - A [i].spend);
    }
    return 0;
}
EDIT: Problem solved. Thank You
