To delete a non repeated element from Array.

Solved!
Go to solution

Hi...,

 

I have a 1D array of elements, I need to delete non repeated elements from that array and also need to print repeated elements only once.

 

Thankyou.

Sounds like typical homework…

 

What have you tried?

Where are you stuck?

Mind to provide your VI with typical input data?

 

You might rephrase your requirement:

"I need to output those elements from an 1D array that occur atleast twice."

Hi Hemanth,

 

and what have your tried so far?

Is the input array always sorted?

 

Suggestion:

  1. Sort the array.
  2. Test, if the first elements is the same as the second.
  3. If unequal then keep that element in the (conditional) output tunnel.
  4. I equal continue the test with the next element(s) until you encounter another value…
Best regards,
GerdW

Hi Hermanth,

 

please downconvert the VI for LV2019… (File->Save for previous)

Best regards,

Hi Hemanth,

Another method would be use InsertIntoSet option in a Loop based on the Size of the Array.

 

Concatenate the Input Element whenever the already Included output array from the InsertIntoSet Function is True.

 

In this case you will miss one element for each unique Array element for example for the input "Test1,Test2,Test2,Test3,Test3,Test3,Test4,Test4,Test4,Test4" You will get "Test2,Test3,Test3,Test4,Test4,Test4" as output you will need to append and short the array after the result.

 

This method will help you to understand how to use Set Function which you may not use frequently.

Hi Hermanth,

 

why do you need so much code? (590kB vs 16kB)

(Just a suggestion, you can make this even simpler…)
