title: Debugged and Reliable Python Solution for XOR Strings Body: Hi everyone! 👋

I faced an issue where the same code sometimes failed hidden test cases and then passed on retry.(reset your page)
Here’s a clean and robust Python solution for the XOR Strings problem:

Python Code

def strings_xor(s, t): res = "" for i in range(len(s)): if s[i] == t[i]: res += '0' else: res += '1' return res

s = input().strip() t = input().strip() print(strings_xor(s, t))

How it works:

1. Compare characters of both strings one by one.
2. If characters are the same → add '0' to the result.
3. If characters are different → add '1' to the result.
4. .strip() ensures no extra spaces cause wrong answers.
5. Return the final XOR string.

✅ This method handles hidden test cases reliably and avoids common issues like extra spaces, leftover debug prints, or newline mismatches.

I really enjoy solving algorithm problems here on HackerRank! It’s a great platform to test and improve coding logic. Recently, I’ve also been exploring AI tools that help in creative areas like photo enhancement and editing, which works great for improving image clarity. It’s interesting how AI is transforming both coding and visual creativity!

Solving the problem efficiently is similar to optimizing data flow in Explore our software, where constraints like order and compatibility must be respected. Here, the challenge is to minimize the number of days needed by forming the longest possible sequences where difficulties strictly increase and vi ratings differ by at least K between consecutive problems.

Problem solving isn’t limited to coding—it’s something we experience in many areas, including games. Open-world sandbox games often push players to think creatively, test different strategies, and adjust quickly when things don’t go as planned. I recently came across Dude Theft Wars, which reminded me a lot of coding challenges because you can approach the same situation in multiple ways. For anyone curious about its gameplay depth, there’s a detailed write-up on Dude Theft Wars Jack that explains the mechanics and tricks: Dude Theft Wars Jack
