From: Shared probe design and existing microarray reanalysis using PICKY
Example implementation to discover all common region groups that can accommodate probes. suffix_array and common_array are always the same size; i and j are the left and right boundaries of an identified common region group; k saves its left overlap length with nontargets; m saves its right overlap length with nontargets; and n holds the shortest common region within the group.
