Pro Tips for DSA Success

Consistent Practice

Solve 2-3 problems daily rather than cramming. Consistency beats intensity.

Understand Patterns

Focus on understanding problem patterns rather than memorizing solutions.

Code Quality

Write clean, readable code with proper variable names and comments.
