In the Julia programming language, the function reset(s) is used to reset a stream s to a previously marked position and remove the mark. It returns the previously marked position. If the stream is not marked, it throws an error.
Reset a stream to a previously marked position:
julia> s = "Hello, World!";
julia> mark(s, 6);
julia> reset(s)
6This example sets a mark at index 6 in the string s and then resets the stream to that marked position.
Handling an error when the stream is not marked:
julia> s = "Hello";
julia> reset(s)
ERROR: ArgumentError: stream is not markedIn this example, an error is thrown because the stream s is not marked before attempting to reset it.
Related functions:
mark(s): Marks the current position in the streams.unmark(s): Removes the mark from the streams.ismarked(s): Checks if the streamsis marked.
Note: The reset function is commonly used in conjunction with the mark, unmark, and ismarked functions to manage stream positions.
