Hi all,

I have a list of data type string and would like to ask is there a logic that can remove duplicate entries but keeping only one entry within the list?

The order does not matter

List
Apple
Boy
Apple
Cat
Dog

I wish to keep only 1 instance of Apple in this case.

 

Could not figure out exactly how to use the loop and a iterator to do so.

Any help appreciated.

You ever figure out a solution to this? The only reply isn’t very helpful.

This is very simple. 
 

  1. Take lstInputData - duplicate values
  2. Create List type variable (lstUniqueItems) - empty
  3. Loop over inputList
  4. Check for if the value is present in lstUniqueItems: If  No → Add it 
  5. Another Loop is just to check the items in the lstUniqueItems (Not needed)
  6. Done ✅
