WebJul 16, 2012 · Create a BIT of size greater than n (no of elements). Iterate through array A ( let j be the index of loop),and for each element A [j] do: 1) Add j-sum (A [j]) to the number of inversions 2) add (A [j], 1) (i.e. add 1 to the position A [j] on BIT. This effectively counts the number of time value A [j] is seen so far) WebA pair ( i, j) is called an inversion of A if i < j and A i > A j. An array A is said to be lexicographically smaller than array B if there exists an index t such that A i = B i, ∀ i < t and A t < B t.
