-        -   starts off great, but by the time it gets past KMP it gets more complicated than it needs to be
-        -   nice explanation of tries
-        -   can be skipped
+        -   Започва супер, но след KMP започва да става излишно сложен
+        -   Добро обяснение на префиксни дървета
+        -   Може да го пропуснете
