Hey… I’ve been stuck at this question for quite some time now… Review: ArrayList Operations – CodeChef: Practical coding for everyone
All sample test cases are passing but still getting wrong answer while submitting… not able to figure out which test case it is failing for

Here’s my code :

import java.util.*;

class Codechef
{
public static void main (String[] args)
{
Scanner read = new Scanner(System.in);
int t = read.nextInt();
for(int i=0; i<t; i++)
{
ArrayList a = new ArrayList();
int n = read.nextInt();
for(int j=1; j<=n; j++){
int ele = read.nextInt();
a.add(ele);
}
// Update the code below to solve this problem
for(int j=0; j<a.size()-1;){
if(j<a.size()-1 && a.get(j)==a.get(j+1) || j>0 && a.get(j)==a.get(j-1)){
a.remove(j);
}
else j++;
}

	    System.out.println(a.size());
	}
}

}

Use two for loops
