Webb8 juni 2024 · Hashing algorithms are helpful in solving a lot of problems. We want to solve the problem of comparing strings efficiently. The brute force way of doing so is just to compare the letters of both strings, which has a time complexity of O ( min ( n 1, n 2)) if n 1 and n 2 are the sizes of the two strings. We want to do better. Webb9 mars 2024 · In simple terms, a hash function maps a significant number or string to a small integer that can be used as the index in the hash table.
