Walkthrough

This PR adds a complete solution for Challenge 17 in Go: a palindrome validator. The implementation consists of an IsPalindrome function that normalizes input to lowercase and alphanumerics, then performs two-pointer comparison, plus a main entry point that reads user input and reports the result.

Changes

Challenge 17 Palindrome Implementation

Layer / File(s)	Summary
Palindrome checking logic challenge-17/submissions/miank1/solution-template.go	IsPalindrome normalizes the input string to lowercase, filters out non-alphanumeric characters into a rune slice, and determines palindrome status by comparing characters from both ends inward.
Interactive main entry point challenge-17/submissions/miank1/solution-template.go	main prompts the user for input, reads a line from stdin, calls IsPalindrome, and prints whether the input is a palindrome.

• RezaSi/go-interview-practice#1669: Adds the same Challenge 17 Go palindrome implementation pattern—an exported IsPalindrome that lowercases, filters alphanumerics, and checks via two-pointer comparison, plus a main that reads stdin and prints the result.
• RezaSi/go-interview-practice#587: Introduces an identical palindrome solution in challenge-17/submissions/*/solution-template.go with IsPalindrome normalization logic and a main that reads from stdin.

Poem

A rabbit hopped through letters and digits so fine,
From "A man, a plan, a canal—Panama!" it signs,
Two pointers dance inward, meeting halfway true,
Is it backwards the same? Yes! Our palindrome flew! 🐰✨
