@Yankit_singh
we assume that you have split on space (blanks) otherwise may we ask to share some more details with us.
the meaning of @
is that the string is handled as a verbatim string literal . It means that escaping isn’t applied.
we do see some additional character (see yellow mark and line break)
after split we also do see that the @
is moved to the part with the line breaking part
but the @
would not be part of the string content.However we suggest to find out what this “hidden” char is of type of.
May we ask for screenshot from watch panel for this string /split item
Also have a look here for an analysis for non displayed chars:
