String Problems

1. Basic String Manipulation:

• Valid Anagram (check if two strings are anagrams)

• Find All Anagrams in a String
• Minimum Window Substring

3. Two Pointer String Problems:

• Compare Version Numbers
• Backspace String Compare
• Long Pressed Name

4. Pattern Finding:

• Find and Replace Pattern
• Group Shifted Strings
• String Compression

Key concepts to focus on:

• String comparison techniques
• Finding all possible solutions (not just one)
• Efficient character matching
• Two-pointer approaches
