    en.wikipedia.org/wiki/FM-index

    C[c] is a table that, for each character c in the alphabet, contains the number of occurrences of lexically smaller characters in the text. The function Occ(c, k) is the number of occurrences of character c in the prefix L[1..k]. Ferragina and Manzini showed [1] that it is possible to compute Occ(c, k) in constant time.
