The left to right is the meaning of first “L” and leftmost derivation is the meaning of second “L”. The left to right is the meaning of first “L” and rightmost derivation is the meaning for “R”...

Explanation of Solution

Bottom-up parser:

The “LR” parser is the bottom-up manner because, they construct a parse tree from the leaves up, recognizing when a collection of leaves can be joined together as the children of a single parent.

It attempts to reduce the input string to start symbol of a grammar.

It first looks at the lowest level of the parse tree and works up the parse tree by using the rules of grammar...

Explanation of Solution

Predictive parser:

The “LL” parser is the predictive parser because, it has the capability to predict which production is to be used to replace the input string.

It does not suffer from backtracking.

A stack and a parsing table is used by the predictive parser to parse the input and generate a parse tree...

Explanation of Solution

LL and LR stands for:

The “LL” stands for Left-to-Right, Leftmost derivation.

It first looks at the highest level of the parse tree and tree by using the rules of grammar, it works down the parse...

.NET Interactive Solving Sudoku using Grover's Algorithm We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm. Turning the Problem into a Circuit We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit that…
