To illustrate document rotation, consider the sequence 'Hard work leads to success . Success brings happiness .'. If a token such as 'leads' is selected, the part of the sequence that precedes it ('Hard work') is moved to the end. This rotation results in the corrupted input: 'leads to success . Success brings happiness . Hard work'.

Example of Document Rotation

A text sequence was altered for a self-supervised learning task by selecting a token and moving the preceding part of the text to the end. The resulting sequence is: 'is a key component of many systems . Artificial intelligence'. What was the original, unaltered text sequence?

Reconstructing Original Text from a Rotated Sequence

A text sequence was altered by selecting a token and moving the preceding part of the text to the end. The two resulting segments are shown below. Arrange them in the correct order to reconstruct the original sequence.

A text sequence is being prepared for a self-supervised learning task. The original sequence is: 'The quick brown fox jumps over the lazy dog.' If the token 'jumps' is selected as the new starting point, what will the rotated sequence be?
