Jan 29, 2026 · Hash Table : Hash table is typically an array of lists. It stores values corresponding to the keys. Hash stores the data in an associative manner in an array where each data value has its own unique index. How does Hashing work? Suppose we have a set of strings {“ab”, “cd”, “efg”} and we would like to store it in a table .
