Summary

In a hash_table, quadratic_probing is an open_addressing method for collision_resolution. When a slot is busy, it tries offsets that grow by squares, forming a probe_sequence like 1, 4, 9, ... modulo the table. This reduces primary_clustering but can still cause secondary_clustering. Keep the load_factor low for expected O(1) inserts and searches. Choose a suitable table_size to ensure full coverage. Deletions often use a tombstone marker so probing continues correctly.
