Select the correct answer.

write an algorithm that reads to values, determines the largest value and prints the largest value with an identifying message

REY [17]

Answer:

I'm unsure of what language you are referring to, but the explanation below is in Python.

Explanation:

a = int(input("Input your first number: "))

b = int(input("Input your second number: "))

c = int(input("Input your third number: "))

maximum = max(a, b, c)

print("The largest value: ", maximum)

Use semaphore(s) to solve the following problem. There are three processes: P1, P2, and P3. Each process Pi has a segment of cod

Lisa [10]

Answer:

See explaination

Explanation:

Here we will use two semaphore variables to satisfy our goal

We will initialize s1=1 and s2=1 globally and they are accessed by all 3 processes and use up and down operations in following way

Code:-

s1,s2=1

P1 P2 P3

P(s1)

P(s2)

C1

V(s2) .

P(s2). .

. C2

V(s1) .

P(s1)

. . C3

V(s2)

Explanation:-

The P(s1) stands for down operation for semaphore s1 and V(s1) stands for Up operation for semaphore s1.

The Down operation on s1=1 will make it s1=0 and our process will execute ,and down on s1=0 will block the process

The Up operation on s1=0 will unblock the process and on s1=1 will be normal execution of process

Now in the above code:

1)If C1 is executed first then it means down on s1,s2 will make it zero and up on s2 will make it 1, so in that case C3 cannot execute because P3 has down operation on s1 before C3 ,so C2 will execute by performing down on s2 and after that Up on s1 will be done by P2 and then C3 can execute

So our first condition gets satisfied

2)If C1 is not executed earlier means:-

a)If C2 is executed by performing down on S2 then s2=0,so definitely C3 will be executed because down(s2) in case of C1 will block the process P1 and after C3 execute Up operation on s2 ,C1 can execute because P1 gets unblocked .

b)If C3 is executed by performing down on s1 then s1=0 ,so definitely C2 will be executed now ,because down on s1 will block the process P1 and after that P2 will perform up on s1 ,so P1 gets unblocked

So C1 will be executed after C2 and C3 ,hence our 2nd condition satisfied.

Use EBNF notation to describe the syntax of the following language constructs.

ZanzabumX [31]

Answer:

Following are the description to the given points:

Explanation:

To resolve basic design restrictions, EBNF has also been developed.This principle was its lack of support can identify repeatings easily. It implies that popular BNF models, like the description of a sequence of replicable elements, are complicated and rely on contra intuitive logical math.

To set a list of words divided by commas (e.g. john, coffee, logic) for instance, we would like to say something like "a list is a word accompanied by a few commas or terms." Through EBNF, they may say so. However, there have been no "many" alternatives in the standard BNF format. So, to describe something such as "a list is a term or a number accompanied by a pair with notation and script," you have to say the same thing. Which functions, although it is difficult, as it specifies a variety of lists instead of a specific list.

Essentially, "john, coffee, logic is John's list, accompanied by coffees or, and logic" would be the earlier link. That's why in Option (a):

The return statement in Java is:

return ('”‘ (~[“] | ” [”e‘])*);

In option (c), it is the valid statement.

Create a method called fixArray(int[][] array, int row, int col, int value) that sets the [row][column] to the correct value. Th

PolarNik [594]

Answer:

public class Main {
public static void main (String [] args) {
int[][] myArray = {{1,5,6}, {7, 9, 2}};
fixArray(myArray, 1, 2, 12);
System.out.println(myArray[1][2]);
}
private static void fixArray(int[][] array, int row, int col, int value){
array[row][col] = value;
}
}

Explanation:

The solution code is written in Java.

Firstly, create the method fixArray with that takes four inputs, array, row, col and value (Line 11). Within the method body, use row and col as index to address a particular element from array and set the input value to it (Line 12).

Next, we test the method in the main program using a sample array (Line 4) and we try to change the row-1 and col-2 element from 2 to 12 (Line 5).

The print statement in Line 7 will display 12 in console.
