Linear Search

This lesson is part of DSA · All levels

Summary

Linear search has the worst-case and average because every element is potentially checked. The best case is when the target is in first position. The advantage is simple and does not require data to be sorted, so it remains relevant for small data or sequential structures.

Key points

Best case scenario when the target is in the starting position
Average and worst
No need for sequencing data
