Walkthrough

Adds a Go solution to challenge-2 that reads a single line from standard input, reverses it using Unicode-aware rune conversion and two-pointer swapping, and prints the result. The ReverseString function handles multi-byte characters correctly by converting to rune slices before reversing.

Changes

String Reversal Challenge Solution

Layer / File(s)	Summary
Main program and ReverseString implementation challenge-2/submissions/Alexandr20-ur/solution-template.go	Implements a complete solution with a main() entry point that reads one line from stdin via bufio.Scanner, calls ReverseString to reverse using rune-based two-pointer swapping, and prints the reversed output.
