NettetHere is my understanding of linear probing. For insertion: - We hash to a certain position. If that position already has a value, we linearly increment to the next position, until we encounter an empty position, then we insert there. That makes sense. My question revolves around lookup.

NettetSuppose, I have a hash table of size 10 and I want to insert following data into it. 1,5,7,87,47,27,97,34,89,10. My hash function is : key % 10. So when I use the above function, what should I do if the index obtained after linear probing (simply placing the data in the next empty index) is greater than the table size. i.e. To add 97 to the table.

Nettet• We discussed three kinds of open addressing: linear probing, quadratic probing, and double hashing. • In linear probing the step size is always 1, so if x is the array index calculated by the hash function, the probe goes to x, x+1, x+2, x+3, and so on. • The number of such steps required to find a specified item is called the probe length.
