Hello Everyone!

The link to the question

The approach I am unable to understand.

I am finding it difficult to how is the author deciding what bits to set in x on basis of S. Mainly the 3rd and 4th paragraph of the solution, I am unable to grasp.

It would be really helpful if someone who was able to understand the approach can describe in his own words.

Thank you
