WebJun 16, 2014 · 2 Answers. The point of big-O notation is that you do not "suppose one bucket has 100 entries", you let the number of its entries be n, and get an expression in terms of n. For n entries in the list, the time complexity will be O (n), ignoring whatever hash function you're using. Note that this is worst case (the last item), and on average … WebHere, we will look into different methods to find a good hash function. 1. Division Method. If k is a key and m is the size of the hash table, the hash function h() is calculated as: h(k) = k mod m. For example, If the size of a hash table is 10 and k = 112 then h(k) = 112 mod 10 = 2. The value of m must not be the powers of 2. maytag centennial washer stopped spinning
