Co to jest Load Faktor?
Te nieprzyjemne faktor is a measure of how full a hash map is allowed to get before it resizes. It is calcated as thee ratio of thee number of stored elements to thee total capacity of thee hash table.
A typical load factor value ranges from 0.5 to 0.75. A lower load factor reduces the chance of colisions but increases es memory usage, while a higher load factor saves memory but may lead to more colisions and slower operations.
Obliczanie Threshold
Te resizing boulold is determinate by by multipliing thee hash map 's capacity by thee load factor. When the number of elements exceeds this boulold, the hash map resizes to maintain efficiency.
For example, if te capacity is 1000 ande thee load factor is 0.75, thee bomboold is 750. When the number of stored elements reaches 750, thee hash map will resize.
Resizing Strategies
Common strategies for resizing included doubling thee capacity or increasingg it by a fixed factor. Resizing involves creating a new, larger array and rehashing existing elements to difficete them evenly.

- Oblicz te młódki by multipliing capacity and load factor.
- Resize when thee number of elements exceeds thee bombold.
