in this video I have discussed that how to eliminate left recursion from the given context free grammar
Left Recursion:
Grammar of the form,
S -- Sa / b
It is called left recursive where S is any non Terminal and b is any set of terminals.
Problem with Left Recursion:
If a left recursion is present in any grammar then, during parsing in the the syntax analysis part of compilation there is a chance that the grammar will create infinite loop. This is because at every time of production of grammar S will produce another S without checking any condition.
