Kicking Off: The First Day of the Grind

💻 Problems Solved:
✅ Contains Duplicate (Easy)
✅ Valid Anagram (Easy)
✅ Two Sum (Easy)
✅ Group Anagrams (Medium)

🔍 Key Takeaways:

• Hashing is powerful! Used HashMaps (or Sets) for quick lookups in most problems.

• Sorting can simplify things. In "Valid Anagram", sorting made comparison easy.

• Edge cases matter. Initially, I missed handling empty strings and single-character cases.

• Group Anagrams was tricky! Using a frequency-count tuple for grouping was a cool trick.

⚡ Reflection:
Day 1 done! 🎯 Started with some array and hash-based problems, and the patterns are already getting clearer. "Group Anagrams" was a step up, but it was a good push. On to Day 2! 🚀
