• Feb 20, 2015 · In my spare time I enjoy solving programming puzzles, often algorithmic or mathematical in nature. Here is an automatically updated list of the problems I’ve solved on some of my favorite online judges.
The Longest Common Prefix (LCP) is the Lowest Common Ancestor (LCA) in a suffix tree. Once you have the Lowest Common Ancestor, you can count the number of nodes that branch out from the LCA. This will give you the number of occurrences of a pattern in the suffix tree. This is the relationship between the LCP and LCA.
