Walkthrough

Adds a Go Challenge 2 command-line solution that reads one line, reverses it by Unicode code point, and prints the result through an exported ReverseString helper.

Changes

Challenge 2 reversal flow

Layer / File(s)	Summary
Unicode-aware reversal helper challenge-2/submissions/WHFF521/solution-template.go	ReverseString converts the input to runes and reverses the slice with two inward-moving indices.
Command-line input and output challenge-2/submissions/WHFF521/solution-template.go	main scans one standard-input line, calls ReverseString, and prints the reversed result.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Poem

A bunny met a string one day,
Then hopped its letters back the way.
Runes danced safely, side by side,
While stdin sent them on a ride.
“Reverse!” cried Bun—and out they flew!
