Find the first character in a stream which is not repeated in the rest of the stream. Please note that you are being provided a stream as a source for these characters. The stream is guaranteed to eventually terminate (i.e. return false from a call to the hasNext() method), though it could be very long. You will access this stream through the provided interface methods. A call to hasNext() will return whether the stream contains any more characters to process. A call to getNext() will return the next character to be processed in the stream. It is not possible to restart the stream. Example: Input: aAbBABac Output: b In this example, the character ‘b’ is the first character in the stream which is not repeated in the stream.
