Please help me


Can you share expected output for the above?


I am learning Ui Path
m larnng i pth >>>>that’s output

with Regards,

currently, there is a difference to your output, but we guess this is about expectations and description

EDIT: Sample is only half implemented

could you please explain it With activity
if you please don’t mind

Create an array of capital and small case Vowels → Use a for each activity → for each item in Input_String → use if else activity inside for each activity-> if item in array then Input_String.replace(item, “”) else continue

Please reply on this if you need excess details regarding the same.

Can you try the following?

yourString = "I am learning Ui Path"
arrVowel = {"a","i","u","e","o"}


String.Join("",yourString.Where(Function(c,i) i mod 2 =1 OrELse not arrVowel.Contains(c.ToString.ToLower)))

newString =  String.Join("",strText.Select(Function (x,i) If(i mod 2 = 0 AndAlso arrVowels.contains(x.toString.ToUpper), "", x.toString)))

Hello sir
I am getting blank output after this


what was done in detail?

I am uploading the image please check this

we cannot see the used detail statement But in general the modelling looks fine.

Just do the prototyping also in within the immediate panel and use the debugging panels for the analysis:
