Left recursion: Applications, Art & Science

In the formal language theory of computer science, left recursion is a special case of recursion where a string is recognized as part of a language by the fact that it decomposes into a string from that same language (on the left) and a suffix (on the right). For instance, 1 + 2 + 3 {\displaystyle 1+2+3} can be recognized as a sum because it can be…
