Answer 2

You could also try to transfer the values of the array to a set. The set will only store the unique values of the array.

Answer 4

// simple java program to remove duplicates array values.
// techie praga codes

class Main
{

// Function

// This function- removeDuplicates (to remove duplicate elements)returns new size of modified array

static int removeDuplicates(int arr[], int n)

{

if (n == 0 || n == 1)

return n;

// To store index of next unique element

int j = 0;

// Doing same as done in Method 1

// Just maintaining another updated index i.e. j

for (int i = 0; i < n-1; i++)

if (arr[i] != arr[i+1])

arr[j++] = arr[i];

arr[j++] = arr[n-1];

return j;

}

public static void main (String[] args)

{

int arr[] = {1, 2, 2, 3, 4, 4, 4, 5, 5};

int n = arr.length;

n = removeDuplicates(arr, n);

// Print updated array

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