Answer:

LIKE.

Explanation:

A structured query language (SQL) can be defined as a domain-specific language designed and developed for managing the various data saved in a relational or structured database.

In Computer programming, any word restricted for use, only in object names because they belong to the SQL programming language are called reserved word.

Hence, these reserved words can only be used as the name of an object but not as an identifier e.g the name of a function, label or variable.

Some examples of reserved words in structured query language (SQL) are UPDATE, GROUP, CURRENT_USER, CURRENT_DATE, CREATE, DELETE etc.

Hence, SQL allows the use of special operators in conjunction with the WHERE clause. A special operator used to check whether an attribute value matches a value contained within a subset of listed values is LIKE.

Which of the following commands uses correct syntax for matching the patterns bunk or bank at the end of a line of text?
Alika [10]

Answer:

a. grep 'b[au]nk$' myLine

Explanation:

grep is a command used for searching a specified pattern in a given text.

Our goal is to match the character sequence - bank or bunk at the end of line in a  given line referenced by myLine.

The regular expression for the specified match criterion is:

b[au]nk$

The second character can be either a or u.

$ indicates match at end of line.

So the overall grep command is :

grep 'b[au]nk$' myLine

You are hired by a game design company and one of their most popular games is The Journey. The game has a ton of quests, and for
Kamila [148]

Answer:

Explanation:

Let's describe the connected part for the very first time.

Component with good connections:-

A semi in any graph 'G' is defined by a way to align element if this can be crossed from the beginning of any link in that pixel or if this can be stated that there is a path across each organized node pair within this subgram.

Consecrated pair means (ni, nj) and (nj, ni) that 2 different pairs would be regarded.

In point a:

We're going to be using contradictions for this segment. They start with the assumption that two lucky journeys are not even in the same strongly interconnected component.

For instance, qi and qj are providing special quests that were not in the very strongly linked element and which implies that, if we start to cross from qi or qi, then qj cannot be approached if we begin to move through qj and as we established if qi or qj is fortunate contests, we may reach any other hunts. Which implies qj from qi or conversely should be reachable. Or we might claim that qi is part of the strongly linked portion of qj or vice versa with this situation.

Consequently, we would not be capable of forming part of a different and strongly linked element for two successful scientists; they must have the same strongly related to the element.

In point b:

Its definition of its strong, line segment indicates that all other searches within such a strongly coordinate system can be made possible from any quest. Because if all quests are accessible from any quest then a lucky search is named, and all other quests can be accessed from any quest in a very coordinated system. So, all contests are fortunate contests in a strongly connected element.

Algorithm:

Build 'n' size range named 'visited' wherein 'n' is the number of graphic nodes that keep records of nodes already frequented.  Running DFS out of every unknown vertex or mark all edges as seen.  The lucky search will be the last unexplored peak.

Psuedo-Code:

Requires this functionality to also be called Solution, it requires 2 reasons as an input, V is a set of objects in graph 'G' and 'G' is a chart itself.

Solution(V, G):

visited[V] = {false}//assign value

for v: 0 to 'V'-1:  //using for loop

if not visited[v]:  //use if block

DFS(v, visited, V, G)  //use DFS method

ans = v //holding value

return ans //return value

Whats the difference between copying a file to my desktop and creating a shortcut?
hram777 [196]
When you copy a file to the desktop you are putting the actual file on the desktop whereas when you put a short cut on the desktop you are just placing a reference to where the file is actually located.
