Answer:
In Java:
import java.util.*;
public class RandomDistributionCheck{
public static void main(String[] args) {
final int iter = 10000000;
final int unique = 20;
Random rd = new Random();
int [] intArray = new int[20];
for(int i =0;i<20;i++){ intArray[i]=0; }
for(int i =0; i<iter; i++){
int rdd = rd.nextInt(20);
intArray[rdd]++; }
System.out.println("Number\t\tOccurrence\tPercentage");
for(int i =0;i<unique;i++){
System.out.println(i+"\t\t"+intArray[i]+"\t\t"+(intArray[i]/100000)+"%");
} } }
Explanation:
This declares the number of iteration as constant
final int iter = 10000000;
This declares the unique number as constant
final int unique = 20;
This creates a random object
Random rd = new Random();
This creates an array of 20 elements
int [] intArray = new int[20];
This initializes all elements of the array to 0
for(int i =0;i<20;i++){ intArray[i]=0; }
This iterates from 1 to iter
for(int i =0; i<iter; i++){
This generates a random number
int rdd = rd.nextInt(20);
This increments its number of occurrence
intArray[rdd]++; }
This prints the header
System.out.println("Number\t\tOccurrence\tPercentage");
This iterates through the array
for(int i =0;i<unique;i++){
This prints the required output
System.out.println(i+"\t\t"+intArray[i]+"\t\t"+(intArray[i]/100000)+"%");
}
