Direct recursion vs indirect recursion
WebA production is immediately left recursive if its left hand side and the head of its right hand side are the same symbol, e.g. B → Bvt A grammar is called immediately left recursive if it possesses an immediately left recursive production. INDIRECT LEFT RECURSION. WebIndirect Recursion A method calling itself is direct recursion, but a sequence of methods that eventually calls the first can result in indirectrecursion. This is often difficult to understand and debug. A higher-level recursive method with subroutine method calls can avoid this confusion.
