Palindrome of string without using Reverse function?

Hello All, I am trying String Manipulation programs, and I am really stuck in this where we need to write a program whether a string is a palindrome or not without using reverse. Run a loop from starting to length/2 and check the first character to the last character of the string and second to second last one and so on …. If any character mismatches, the string wouldn’t be a palindrome —> this is the logic, however in UiPath I’m not able to write the piece of code how Subsrting or IndexOf & L…

Thanks,
Ashok

Hi @naresh.kuruva

Try this

Input.ToLower().SequenceEqual(Input.ToLower().Reverse())

Or

@naresh.kuruva

without using built in functions

Here’s a step-by-step explanation of the UiPath workflow along with the code:

Input Dialog: This activity prompts the user to enter a string and stores it in the variable inputString.

Assign Initial Values: This activity initializes the variables left and right. left is set to 0 and right is set to the length of the input string minus 1.

While Loop: This loop iterates as long as the left index is less than the right index. Inside the loop, it checks if the characters at positions left and right in the string are equal.

If Condition: Inside the loop, there’s an If activity that checks if the characters at positions left and right are equal. If they are, it sets the result variable to True.

Increment and Decrement: After each iteration, the left index is incremented by 1 and the right index is decremented by 1.

Result Message Box: Finally, after the loop completes, there’s an If activity to check the value of the result variable. If it’s True, it displays a message box saying that the string is a palindrome. Otherwise, it displays a message box saying that the string is not a palindrome.
