Challenge 1: Multiple Cursors vs. Find-and-Replace With Per-Line Exceptions — Solution Walkthrough

Why multiple cursors handles this better:

Per this chapter's own warning box, find-and-replace applies one
fixed transformation blindly to every match — it has no way to
additionally tweak two specific lines differently from the other
three while still renaming the variable everywhere. A single
find-and-replace pass would need to be run once for the rename, then
followed by separate manual edits to the two lines needing extra
changes, adding steps and risk of missing one.

How multiple cursors handles it in one pass:

Placing a cursor at each of the five occurrences (via Ctrl+D or
Ctrl+Click) lets you retype the variable name at all five locations
simultaneously — but because each cursor still represents a live,
independent editing position, you can also move to just the two
special-case cursors afterward and make their additional tweak
directly, all within the same editing session, without a second
separate pass through the file.

Why this matches the chapter's own core distinction:

This is exactly the "interactive, per-location control" advantage the
chapter's own warning box describes — multiple cursors let the extra
tweaks happen naturally as part of the same edit, rather than
requiring a completely separate step because find-and-replace has no
concept of "these two occurrences are slightly different."

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise applies this chapter's own multiple-cursors-vs-find-and-
replace distinction to a concrete scenario specifically designed to
need per-location judgment, correctly identifying why multiple cursors
handles it more directly.
