Inverse of Generator of Cyclic Group is Generator/Proof 2
Theorem
Let $\gen g = G$ be a cyclic group.
Then:
$G = \gen {g^{-1} }$
where $g^{-1}$ denotes the inverse of $g$.
Thus, in general, a generator of a cyclic group is not unique.
Proof
Let $C_n = \gen g$ be the cyclic group of order $n$.
By definition, $g... | finemath |

Given an array A, we call (i, j) an important reverse pair if i < j and A[i] > 2*A[j]. Count the number of important reverse pairs.
For this kind of problem, Segment Tree and Binary Indexed Tree seem to be the first choice. However, let's look at a more natural (i.e. easier to understand) solution u... | finemath |
