What is the load factor for an open addressing technique?a)Zerob)0.5c)1d)1.5

The load factor for an open addressing technique is c) 1.

Here's why:

The load factor (α) for open addressing in hash tables is defined as the number of entries (n) divided by the number of slots (m) in the hash table. In open addressing, each slot in the hash table can hold exactly one entry, so the maximum load factor is 1.

If the load factor exceeds 1 (i.e., there are more entries than slots), then there would be a collision, and the hash table would need to be resized to accommodate the extra entries. Therefore, the load factor for an open addressing technique cannot exceed 1, ruling out option d) 1.5.

On the other hand, a load factor of 0 would mean that the hash table is empty, and a load factor of 0.5 would mean that the hash table is half full. Therefore, options a) Zero and b) 0.5 are possible load factors, but they are not the maximum load factor for an open addressing technique.

So, the correct answer is c) 1.
