Introduction to DSA & Index
Welcome to the Aruvili DSA Interactive Study Companion. This interactive sheet is designed to help you recall syntax, time complexities, and coding blueprints in Java and Python while solving problems. Use the index below to jump straight to any section.
Complexity Guide (Big-O)
Always analyze performance parameters before coding. Check constraints to see what complexity matches:
O(1) Constant time
O(log n) Logarithmic split
O(n) Linear traversal
O(n log n) Sorting bound
