Quadratic probing is a collision resolution technique used in hash tables, where the algorithm finds an open slot by checking successive positions based on a quadratic function of the number of attempts made to insert a new key. This method helps in distributing the keys more uniformly across the table compared to linear probing, thus reducing clustering issues. Quadratic probing utilizes a formula that increases the search distance for each subsequent attempt, effectively spreading out the occupied slots and improving overall performance.
congrats on reading the definition of quadratic probing. now let's actually learn it.
