Use a single array of Objects, elements can either be null (free slot), String (full slot) and special private static final Object TOMBSTONE = new Object(); for lazily deleted slots....

Here are some solutions I can think about: A quick and dirty fix is to declare a dummy default second parameter, which will not be used, for the one-parameter probe functions, like inline int linear_probe( int i, int dummy = 0 ) { return i; } Now linear_probe has effectively...

The implication is that at some point (when you would exceed a load factor of 0.5 in this case), you'll have to allocate a new table (which is bigger by some factor, maybe 1.5 or 2, and then rounded up to the nearest prime number) and copy all the elements...

There must be a proof for this out there somewhere. But, I don't see how quadratic probing could hit every bucket in most cases. Let's say the table size is 7, and h(k) is 0. For the ith iteration, probe = i^2 mod 7. I tested all i less than...
