We consider the model of hashing with linear probing and we establish the moderate and large deviations for the total displacement in sparse tables. In this context, Weibull-like-tailed random variables appear. Deviations for sums of such heavy-tailed random variables are studied in Nagaev (Theory...
In open addressing, all the keys will be stored in the hash table itself, not by using any additional memory or extending the index(linked list). This is also known asclosed hashingand this is done mainly based on probing. Probing can be done based oneither linear probing or quadratic pro...
Collision resolution with linear probing Once we have built a hash table using open addressing and linear probing, it is essential that we utilize the same methods to search for items. Assume we want to look up the item 93. When we compute the hash value, we get 5. Looking in slot 5 ...

In this we can see 67, 90 and 55 can be inserted in a hash table by using first hash function but in case of 17 again the bucket is full and in this case we have to use the second hash function which is H2(key)=P-(key mode P) here p is a prime number which should be take...
On the other hand, we can get constant worst-case search time, at least in expectation, by using a table of roughly quadratic size, but that seems unduly wasteful. Fortunately, there is a fairly simple way to combine these two ideas to get a data structure of linear expected size, whose...

题目要求是给出了hashing的结果,而且是用的linear probing线性探测解决冲突,要求给出初始序列。负数直接跳过,序列中的数都是非负数。所以遍历给出序列,如果说当前位置的s[i] % n等于i那么就是说不存在冲突,如果不相等就是存在冲突的,经过线性探测才存在当前位置,所以从s[i] % n位置到i之前的数都是比是s[i]...
