Ver mais WebA hash table is a container data structure that allows you to quickly look up a key (often a string) to find its corresponding value (any data type). Under the hood, they’re arrays that are indexed by a hash function of the key. A hash function turns a key into a random-looking number, and it must always return the same number given the same key. how to sprout a coconut seedling
