Which of the following shows a list of Big-Oh running times in order from slowest to fastest?

Rufina [12.5K]

Answer:

O(N!), O(2N), O(N2), O(N), O(logN)

Explanation:

N! grows faster than any exponential functions, leave alone polynomials and logarithm. so O( N! ) would be slowest.

2^N would be bigger than N². Any exponential functions are slower than polynomial. So O( 2^N ) is next slowest.

Rest of them should be easier.

N² is slower than N and N is slower than logN as you can check in a graphing calculator.

NOTE: It is just nitpick but big-Oh is not necessary about speed / running time ( many programmers treat it like that anyway ) but rather how the time taken for an algorithm increase as the size of the input increases. Subtle difference.

Nuetrik [128]

Object-oriented databases is more flexible and stores data as well as instructions to manipulate the data.

A system known as an object database uses object-oriented programming to represent data in the form of objects. Different from relational databases, which are table-oriented, are object-oriented databases.

The concept of object-oriented programming languages, which is currently popular, is the foundation of the object-oriented data model. Overloading, polymorphism, and inheritance Object-oriented programming fundamentals that have found use in data modelling include object-identity, encapsulation, and information hiding with methods to provide an interface to objects. The rich type system, which includes collection and structured types, is supported by the object-oriented data model as well.

In contrast to relational databases, which can only handle one type of data, object databases can handle multiple data types. Unlike conventional databases like hierarchical, network, or relational, object-oriented databases can handle a variety of data types, including text, numbers, images, voice, and video.

Also, Reusable code, realistic modelling, and increased dependability and flexibility are all provided by object-oriented databases.

<h3>What is diagnostic and troubleshooting?</h3>

Diagnosing is known to be the act of finding out the root cause of any issue through an act of elimination but troubleshooting is known to be the act of fixing of the problem after diagnosis is said to have been carried out.

Everybody at a company is assigned a unique 9 digit ID. How many unique IDs exist?

Brut [27]

If you include all zeroes, then it should be 1,000,000,000. Otherwise it’s 999,999,999.

Think of how between 0-9 theres 10 numbers, and use that logic towards 000000000-999999999

What is the best use of a line chart?

lapo4ka [179]

Line graphs can also be used to compare changes over the same period of time for more than one group. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time. Bar graphs are used to compare things between different groups or to track changes over time.
