WebFeb 14, 2013 · Basically, this works by dividing your array into 64-word chunks and assigning one 64-bit index to each chunk. A bit of the index word is set iff the corresponding bitset word has all bits set. When you change a bit in the bitset, you adjust the corresponding index word. You can then build another index array on top to form a tree.
