📚 Understanding O(N) Linear Complexity

O(N) means the number of operations grows linearly with input size N.

Single loop (O(N)): Visit each element once → N steps total
Double loop (O(2N)): Two passes through array → 2N steps (still O(N)!)
Triple loop (O(3N)): Three passes → 3N steps (still O(N)!)
Key insight: O(2N), O(3N) are all simplified to O(N) because constants don't matter for Big-O
