Understand Linear Probing in Hash Maps. Watch how the algorithm finds the next available slot when collisions occur.
Linear Probing is an Open Addressing technique. When a collision occurs, the algorithm "probes" the very next available slot in the array until an empty one or the target key is found.
If the target slot is occupied by a different key, we increment the index (circularly) and check again.
The search ends when the key is found, an empty slot is reached, or the entire table has been probed.
Linear Probing requires the Load Factor to stay below 0.7 to avoid "Clustering" which severely impacts performance.
