How are duplicates removed from a given array?

We can remove duplicate element in an array by 2 ways: using temporary array or using separate index. To remove the duplicate element from array, the array must be in sorted order. If array is not sorted, you can sort it by calling Arrays. sort(arr) method.

How does HashMap find duplicates in array?

How do you remove duplicates in unsorted array?

Approach :

1. Take a hash map, which will store all the elements which have appeared before.
2. Traverse the array.
3. Check if the element is present in the hash map.
4. If yes, continue traversing the array.
5. Else Print the element.

How can you remove duplicates in an array in C?

Algorithm to remove duplicate elements in an array (sorted array)

1. Input the number of elements of the array.
2. Input the array elements.
3. Repeat from i = 1 to n.
4. – if (arr[i] != arr[i+1])
5. – temp[j++] = arr[i]
6. – temp[j++] = arr[n-1]
7. Repeat from i = 1 to j.
8. – arr[i] = temp[i]

How do you find duplicates in an array if there is more than one duplicate?

Algorithm

• Declare and initialize an array.
• Duplicate elements can be found using two loops. The outer loop will iterate through the array from 0 to length of the array. The outer loop will select an element.
• If a match is found which means the duplicate element is found then, display the element.
