It can obtain the prefix sum in O (log N) time, add or update one item in O (log N) time, random-access in O (1) time. At the same time, we provide a **random access iterator** of the prefix sum. The iterator can interact well with many STL algorithms. sims 4 movies override

"WebThe final step in the binary indexed tree is to note that because of this bitwise trickery, we don't even need to have the tree stored explicitly anymore. We can just store all the nodes in an array of length n, then use the bitwise twiddling techniques to navigate the tree implicitly. In fact, that's exactly what the bitwise indexed tree does ...
