[12]. Our extension is twofold: we first show how to compute simultaneously the longest common prefix (LCP) array as well as the BWT, using constant additional space; we then show how to build the LCP array directly in compressed representation using Elias coding, still using constant additional space and with no asymptotic slowdown. Furthermore, we provide a time/space tradeoff for our algorithm when additional memory is allowed. Our algorithm runs in quadratic time, as does Crochemore et al.'s, and is supported by interesting properties of the BWT and of the LCP array, contributing to our understanding of the time/space tradeoff curve for building indexing structures.
