The drawback is that a significant quantity of data is skipped without being checked for additional problems. The benefit is that it is simple to implement and ensures that you do not end up in an infinite loop. Delimiters such as or are synchronizing tokens. This approach involves removing consecutive characters from the input one by one until a set of synchronized tokens is obtained. There are some of the errors that are detected during the syntactic phase recovery:

Creating error procedures that can alter the top of the stack and/or certain symbols on input in a way that is acceptable for table error entries.

Programmer mistakes that call error procedures in the parser table are determined based on the language.

Syntactic Phase Recovery Follows the Given Steps: LR Parser Basically Uses the Mentioned Two Techniques to Detect Errors: Goto entries can never be used to detect errors. When the parser checks the table and discovers that the relevant action item is empty, an error is recognized in LR parsing. Before notifying a mistake, a CLR parser never performs a single reduction and an SLR or LALR may do multiple reductions, but they will never move an incorrect input symbol into the stack. When there is no valid continuation for the input scanned thus far, LR parsers report an error.
