WebMar 1, 2014 · Computing LF from BWT and the C-array. From this perspective, it is immediately clear that Algorithm 2 can be used to compute L F rev along with BWT rev . To be precise, if the c o u n t array is initialized as in Algorithm 3 , then the procedure call bwtrev ( 1 , [ 1 . . n ] , 0 ) computes BWT rev as well as L F rev .
