Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What does the second L in LL(1) represents?
A
Scanning Left to Right
B
Left Most Derivation
C
Left Hand Side
D
Left Most Non-Terminal
Explanation: 

Detailed explanation-1: -The first L indicates that the input is read from left to right. The second L says that it produces a left-to-right derivation.

Detailed explanation-2: -In the name LL(1), the first L stands for scanning the input from left to right, the second L stands for producing a leftmost derivation, and the 1 stands for using one input symbol of lookahead at each step to make parsing action decision.

Detailed explanation-3: -It is used to parse the large class of grammars. In the LR parsing, “L” stands for left-to-right scanning of the input. “R” stands for constructing a right most derivation in reverse.

Detailed explanation-4: -Recognizing LL(1): Here are two properties we know must be true of a grammar if it is to be LL(1): the grammar must not be left recursive. the rule which should be chosen when developing a nonterminal must be determined by that nonterminal and the (at most) next token on the input.

Detailed explanation-5: -Explanation: LR stands for Left to right and rightmost derivation in reverse.
