Efficient Range Minimum Queries using Binary Indexed Trees
... nodes are indexed from 1 to N with labels written in binary, and it uses this binary representation to define the parent node for each node. BITs are in fact the binomial trees of (Cormen et al., 1990). We construct them inductively, starting with B0, a tree with a single node. We will construct ...

... Octal and Hexadecimal Notation • Because binary notation tends to get rather long, computer scientists often prefer octal (base 8) or hexadecimal (base 16) notation instead. Octal notation uses eight digits: 0 to 7. Hexadecimal notation uses sixteen digits: 0 to 9, followed by the letters A through ...

... To convert decimal to octal is slightly more difficult. The typical method to convert from decimal to octal is repeated division by 8. While we may also use repeated subtraction by the weighted position value, it is more difficult for large decimal numbers. Repeated Division By 8 For this method, di ...

Suppose we would like to prove that a property P holds for every n ∈ N; we can first prove that P (Z) holds; we then prove that P (n) implies P (S(n)) for every n ∈ N. This is ...
