Answer:

Hi!

Let's make a quick debug of the code:

i j Output

0+0 = 0

0+1 = 1

0+2 = 2

0+3 = 3

1+0 = 1

1+1 = 2

1+2 = 3

1+3 = 4

2+0 = 2

2+1 = 3

2+2 = 4

2+3 = 5

3+0 = 3

3+1 = 4

3+2 = 5

3+3 = 6

4+0 = 4

4+1 = 5

4+2 = 6

4+3 = 7

The total outputs is 20.

Explanation:

In the first iterations of the loop for the final value of the i is 1 and the final condition to stop of the do while is (i < 5) , so the iteration of for continues many times until i break the condition.

(5*4 = 20)

And after that you get 20 outputs.

I hope it's help you.

Consider the algorithm for determining whether a sequence of parentheses is balanced (has correct nesting). The pseudo code for

Katarina [22]

Answer:

Explanation:

The maximum number of symbols that will be on the stack would be 3. This is because according to the pseudocode every time that a left-facing symbol ( }, ], or ) ) it automatically ends the function or pops the last element in the stack. Therefore, the longest sequence of right-facing symbols would also equal the maximum number of symbols in the stack. In the sequence passed in the question, this would mean that the longest stack would be 3 and include the following sequence {[(

Evaluate the expression. Be sure to list a value of appropriate type (e.g., 7.0 rather than 7 for a double, Strings in quotes).

Mashutka [201]

<h2>Answer:</h2>

14.0

<h2>Explanation:</h2>

Using the level of precedence in Java,

From left to right;

(i) the first division operation will be done.

(ii)followed by the second division operation.

(iii)followed by the first multiplication operation.

(iv)followed by the third division operation.

(v)followed by the second multiplication operation.

(vi) followed by the first addition operation.

(vii)lastly followed by the second addition operation.

=================================================

Taking the steps above one after the other;

(i) the first division operation will be done (i.e 19 / 2)

=> Integer division in Java gives an integer result. Therefore, 19 / 2 = 9.5 will give 9.

So,

=> 19 / 2 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4

=> 9 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4

(ii)followed by the second division operation. (i.e 9 / 2.0)

=> From the result from step (i), the second division operation is now 9 / 2.0.

=> 9 / 2.0 = 4.5

So,

=> 9 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4

=> 4.5 + 2.5 * 6 / 2 + 0.5 * 4

(iii)followed by the first multiplication operation. (i.e 2.5 * 6)

=> The first multiplication operation is given by 2.5 * 6

=> 2.5 * 6 = 15.0

So,

=> 4.5 + 2.5 * 6 / 2 + 0.5 * 4

=> 4.5 + 15.0 / 2 + 0.5 * 4

(iv)followed by the third division operation. (i.e 15.0 / 2)

=> The third division operation is given by 15.0 / 2

=> 15.0 / 2 = 7.5

So,

=> 4.5 + 15.0 / 2 + 0.5 * 4

=> 4.5 + 7.5 + 0.5 * 4

(v)followed by the second multiplication operation. (i.e 0.5 * 4)

=> The second multiplication operation is given by 0.5 * 4

=> 0.5 * 4 = 2.0

So,

=> 4.5 + 7.5 + 0.5 * 4

=> 4.5 + 7.5 + 2.0

(vi) followed by the first addition operation. (i.e 4.5 + 7.5)

=> The first addition operation is given by 4.5 + 7.5

=> 4.5 + 7.5 = 12.0

So,

=> 4.5 + 7.5 + 2.0

=> 12.0 + 2.0

(vii) lastly followed by the second addition operation. (i.e 12.0 + 2.0)

=> The second addition operation is given by 12.0 + 2.0

=> 12.0 + 2.0 = 14.0

So,

=> 12.0 + 2.0

=> 14.0

Therefore, 19 / 2 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4 = 14.0

In Java, the order of precedence for arithmetic operators is;

=> /, * and %

=> followed by + and -

Which of the following is the safest authentication method?

myrzilka [38]

The safest authentication method is authentication using a smart card.

Smart Card Authentication uses a physical card along with a smart card reader and software on the workstation to validate users into enterprise resources like workstations and applications. Although smart card authentication offers a terrible user experience and is expensive to deploy and maintain, it is very secure.

Because smart card authentication requires a physical credential, a hardware card reader, and software, it is expensive and difficult to administer. Smart cards are only used in the most secure workplaces, such as three-letter agencies of the federal government or privileged access at a financial institution, as these environments frequently forbid employees from carrying smartphones to and from work.
