The Jolly Beggar was published in Herd's "Scots Songs" in 1776, 41 years before Byron's letter, and goes partially
LL parser main types of LL(1) conflicts: The FIRST sets of two different grammar rules for the same non-terminal intersect. An example of an LL(1) FIRST/FIRST conflict: FIRST(E) = {'b', ε} and FIRST(E 'a') = {'b', 'a'}, so when the table is drawn, there is conflict under terminal 'b' of production rule S. Left recursion will cause a FIRST/FIRST conflict with all alternatives. The FIRST and FOLLOW set of a grammar rule overlap. With an empty string (ε) in the FIRST set it is unknown which alternative to select. An example of an LL(1) conflict: The FIRST set of A now is
