Description -- A typing error in the book and a markup error

Current (Wrong) Text -- * We run a for** loop** from 1 to n with step size of 3.

Corrected (New) Text -- * We run a for loop from 1 to n with step size of 3.

Additionally -- "step size" should be replaced by "stride" as it better suits the original Bulgarian text and the idea the writer wanted to convey.
