Answer:

001*|1*00

Explanation:

The language consists of strings in {0,1} that either start with 00 or end with 00 and have no more zeros.

The requirement can be divided into two parts:

1) Strings that start with 00 and have no more zeros

2) Strings that end with 00 and have no more zeros

Generating regular expressions for these parts:

1) 001*  - starts with two zeros and can have zero or more 1s later

2)1*00  - starts with zero or more 1s and ends with two zeros

So on combining with the or operator(|), the overall regular expression for the strings in the language becomes:

001*|1*00

Answer:

Flowchart of an algorithm (Euclid's algorithm) for calculating the greatest common divisor (g.c.d.) of two numbers a and b in locations named A and B. The algorithm proceeds by successive subtractions in two loops: IF the test B ≥ A yields "yes" or "true" (more accurately, the number b in location B is greater than or equal to the number a in location A) THEN, the algorithm specifies B ← B − A (meaning the number b − a replaces the old b). Similarly, IF A > B, THEN A ← A − B. The process terminates when (the contents of) B is 0, yielding the g.c.d. in A. (Algorithm derived from Scott 2009:13; symbols and drawing style from Tausworthe 1977).

A disgruntled employee can harm a company by launching a computer virus, changing or deleting files, or exposing system password
Setler [38]

Answer:

Threat disgruntled employees

Explanation:

This is a type's threat in a network, why disgruntled employees is a threat?

Because disgruntled employees can implement a plant to damage a company's system when an IT employee be fired.

I t can be difficult to try to protect a system of these threats, Traditionally companies can wait for the less damage, then delete those credentials.

In cloud computing we have IDaaS, where an external company administers the company's credentials, is harder to damage the system in this way.

Charra [1.4K]

Answer:

The delimiter use is "::".

Explanation:

The Java inbuilt String.split( ) function is use to split a String into an array of String.

The split( ) takes delimiter as arguments/parameter which determines at which point the string is to be broken down into different part/token.

From the above code snippet;

Each line in the file a.txt that is not null is splitted using the statement below:

String[ ] v = line.split("::");

The line is splitted using "::" as delimiter and the resulting array is then assigned to the variable 'v'.

For instance, a line in the file could take the form:

John::Smith::Music

When it is splitted,

String lname = John;

because lname make reference to index 0 of the array.

String fname = Smith;

because fname make reference to index 1 of the array.

String dept = Music;

and dept make reference to index 2 of the array.
