Walkthrough

A new Go solution file is introduced that implements a string reversal program. The implementation reads a single line from standard input, reverses the string using an exported ReverseString function that converts input to runes and performs in-place character swapping, and outputs the result.

Poem

🐰 A string walks in backwards today,
Through rune-swapping magic at play,
From left to the right, we flip every bite,
Till palindromes smile in their way! ✨
