What is offset in LZ77 approach?

- The sequence encoding in the look ahead buffer is encoded in this technique.

- The encoding id done by moving the encoder to a search pointer.

- The search pointer is through until a match to the first symbol is encountered.

- This symbol is available in the look ahead buffer.

- The actual distance between the pointer and the look ahead buffer is known as offset.
