Solution
The purpose of a load factor in a hash table is to measure how full the hash table is. The load factor is typically a value between 0 and 1, and it's calculated by dividing the number of entries by the number of buckets in the hash table. When the load factor exceeds a certain threshold, the hash table may need to be resized to accommodate more entries and maintain efficient operations.
