Expert Solution

Program Instruction

The program initializes a user define array and passes it to the function zeroFirst.
In zeroFirst the array is copied to another array for comparison purposes.
First an if condition is used to check index is greater than 1. If it is greater than 1 then another condition comparing and equating previous 2 elements is checked. If they are equal then the first occurrence is changed to zero.
The resultant array is printed.

Program

import java.util.*;

public class ZeroFirstDuplicate {
public static void main (String[] args) {

int n;
Scanner s = new Scanner(System.in);

System.out.print("Enter no. of elements you want in array: (max 100): ");
n = s.nextInt();
int a[] = new int[n];

System.out.print("Enter elements of array: \n");

for (int i = 0; i < n; i++)
{
a[i] = s.nextInt();
}
zeroFirst(a);

int caseNum = 1;
ZeroFirstDuplicate.run(caseNum);

s.close();
}

private static void run(int caseNum) {
// TODO Auto-generated method stub

}

public static void zeroFirst(int[] a) {
int b[] = a;
int i;

for(i = 0; i < a.length; i++)
{
if(i > 1)
{
if(a[i - 2] == b[i - 1])
{
a[i - 2] = 0;
i++;
}
}
}
for(i = 0; i < a.length; i++)
System.out.println(a[i]);
}
}
