A parser is called a shift-reduce algorithm, because in most cases it either shifts the next lexeme of input onto the parse stack or reduces the handle that is on top of the stack.

A LR parser is called a shift-reduce algorithm, because in most cases it either shifts the next lexeme of input onto the parse stack or reduces the handle that is on top of the stack.

Explanation:

A parser is that aspect of the compiler which practices a token string as input and with the sustenance of enduring grammar, transforms it into the identical parse tree. The LR parser is a non-recursive, shift-reduce, bottom-up parser. It utilizes a broad range of context-free grammar which gives it the most valuable syntax analysis procedure.

LR means that the data is examined left-to-right and that a rightmost source, in reverse, is assembled. LR parsers relish time and space extended in the size of the input. Practically all programming languages possess LR grammars.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
