🧠 Logic Implementations

Located in:

app/Logic/Solutions.php

🔸 Task 3: Longest Substring Without Repeating Characters

• Technique: Sliding Window + Hash Map
• Time Complexity: O(n)
• Example:

Input: "abcabcbb"
Output: 3

---

🔸 Task 4: Group Anagrams

• Technique: Sorting + Hash Map
• Time Complexity: O(n * k log k)
• Example:

Input: ["eat","tea","tan","ate","nat","bat"]
Output: [["eat","tea","ate"],["tan","nat"],["bat"]]
