Explanation / Answer

a. Program:

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.util.*;

public class FundRaising {

public static void main(String[] args) throws Exception {

int i, j, n, temp, temp1, noOfSponsorsPerCouple = 0, coupleId, maxEarnCoupleId = 0, maxEarnNoOfSponsor = 0;

float temp2;

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

System.out.println("Enter the number of couples");

System.out.println("--------------------------------------------------------------------------------------");

for (i = 0; i < n; i++) {

/*

* Calculating total number of sponsors, total number of couples and the

* total amount in dollars collected in the campaign. Here the rows with

* same id are treated as same couple

*/

System.out.println("Total count of all couples........");

System.out.println("--------------------------------------------------------------------------------------");

for (i = 0; i < n; i++) {

maxCouples.add(id[i]);

totalAmt += amt[i] * hrs[i];

}

System.out.println("Sponsors count = " + n + " , Number of couples = " + maxCouples.size() + " , Total amount collected = " + totalAmt + "$");

System.out.println();

/*

}

}

}

Enter amount
4.75

c.Output:

Sorted values.............
--------------------------------------------------------------------------------------
id = 117 , hours = 3 , amount = 2.25$
id = 117 , hours = 5 , amount = 1.0$
id = 117 , hours = 5 , amount = 0.8$
id = 132 , hours = 3 , amount = 3.75$
id = 132 , hours = 3 , amount = 1.5$
id = 141 , hours = 1 , amount = 10.0$
id = 141 , hours = 2 , amount = 4.0$
id = 141 , hours = 2 , amount = 2.0$
id = 141 , hours = 5 , amount = 0.65$
id = 157 , hours = 4 , amount = 4.75$
id = 161 , hours = 4 , amount = 4.5$
id = 161 , hours = 6 , amount = 3.4$

Total count of all couples........
--------------------------------------------------------------------------------------
Sponsors count = 12 , Number of couples = 5 , Total amount collected = 114.15$

Total count per couple basis.......................
--------------------------------------------------------------------------------------
Couple id = 117 , Number of sponsors for couple = 3 , Total Amount per couple = 15.75$
Couple id = 132 , Number of sponsors for couple = 2 , Total Amount per couple = 15.75$
Couple id = 141 , Number of sponsors for couple = 4 , Total Amount per couple = 25.25$
Couple id = 157 , Number of sponsors for couple = 1 , Total Amount per couple = 19.0$
Couple id = 161 , Number of sponsors for couple = 2 , Total Amount per couple = 38.4$

Max earn couple details..............
--------------------------------------------------------------------------------------
Couple id = 161 , Number of sponsors = 2 , Total amount they collected = 38.4$
