Remove odd indexed characters from a given string

[Sohil_bagwan1 (Sohil bagwan)]

Input: str = “abcdef”
Output: ace
Explanation:
The characters ‘b’, ‘d’ and ‘f’ are present at odd indices, i.e. 1, 3 and 5 respectively. Therefore, they are removed from the string.

Input: str = “geeks”
Output: ges

by using UiPath how we do that

One way would be to use substring:

str_input = "abcdef"

str_output = str_input.Substring(0, 1) + str_input.Substring(2, 1) + str_input.Substring(4, 1)

Hi @Sohil_bagwan1

1. Use an Assign activity and give the input say inputString.

inputString = "abcdef"

2. Use another Assign activity for output say resultString.

resultString = ""

3. Use for Each activity and give the below condition:

inputString.ToCharArray()

4. Use If activity inside for each activity and give the below condition:

inputString.IndexOf(currentChar) Mod 2 = 0

5. in then sequence of If activity use assign activity save the result to resultString initialized before.

resultString = resultString + currentChar.ToString

6. Print the value of resultString in writeline or message Box.

Note: Attached the workflow for better understanding and reference.

Hi,

Can you try the following expression?

String.Join("",yourString.Where(Function(c,i) i mod 2=0))
