From what I read, the load factor of a hashtable is defined as n/N where n=number of items N=Number of buckets in the hash table
Its recommended you increase the size of your hashtable when load factor is 0.75
Now my question is this
If I have 75 items in my list and the size of the hashtable is 100, is it not possible that multiple items are in the same bucket? Which means I could also be using just 40 buckets. So why not resize when number of buckets used reaches close to 100 instead of looking at number of items?
