A parser is a phase of a compiler that converts a token string into the corresponding Intermediate Representation (IR) using existing grammar. It is classified into two types: Top-down Parser and Bottom-up Parser. Top-down parsers generate parse trees using grammar productions, such as expanding non-terminals and using recursive descent or non-recursive descent parsers. Bottom-up parsers compress terminals and use the reverse of the rightmost derivation. Bottom-up parsers are classified into LR and Operator precedence parsers. Operator precedence parsers generate parse trees from given grammar and string, but only require two consecutive non-terminals and epsilon not appearing on the right-hand side of any production. Operator grammars are considered operator grammars if there is no production rule on the right-hand side.

sir, as Top Down parser doesn't accept Left Recursive grammar, hence
we have to eliminate Left Recursion from
A --> Abc | b

to,

A --> b A'
A' --> b c A' | ε

if I'm wrong please correct me 🙏.
