WebOct 29, 2008 · Insertion and lookup on a trie is linear with the lengh of the input string O (s). A hash will give you a O (1) for lookup ans insertion, but first you have to calculate the hash based on the input string which again is O (s).

WebRolling hash is used to prevent rehashing the whole string while calculating hash values of the substrings of a given string. In rolling hash,the new hash value is rapidly calculated given only the old hash value.Using it, two strings can be compared in constant time. Example A rolling hash (also known as recursive hashing or rolling checksum) is a hash function where the input is hashed in a window that moves through the input. A few hash functions allow a rolling hash to be computed very quickly—the new hash value is rapidly calculated given only the old hash value, the old value removed from the window, and the new value added to the window—similar to the way a moving average function can be computed …
