}

Explanation:

Inside the action performed method, pass the strings in text box.
check if the value has been modified then do the relevant conversions inside the conditional statement.
When the user clears, it will not do to the inch conversion.

Alexxx [7]

Answer: HTML is a language that is used to create Web pages.

Explanation:

HTML (Hypertext Markup Language) simply refers to the code which is used for the structuring of a web page and its content. e.g the content can be structured by using images, in data tables or within a set of paragraphs.

Therefore, the correct statement about HTML is that HTML is a language that is used to create Web pages.

what do we know about the contents of the arrays left and right with respect to what objects (integers) they contain in general

KIM [24]

A "divide and conquer" approach known as binary search necessitates sorting the starting array first. Because the technique divides the array into two equal halves, it is called a binary algorithm. A binary search will initially examine the middle item in the array and evaluate it in relation to the search terms.

<h3>What exactly is binary search?</h3>

Finding an element's location in a sorted array can be done using the searching method known as binary search.
With this method, an array's middle is always searched for the element. Only on a list of things that has been sorted can binary search be used. If the elements are not sorted already, we need to sort them first.
Binary search is used to find values in any sorted collection from any language library, including Java,.NET, C++ STL, etc.
A sorted array can be searched using the binary search algorithm by continually halving the search interval. Utilizing the knowledge that the array is sorted, binary search attempts to minimize the time complexity to O (Log n).

2. Identify two real-world examples of problems whose solutions do not scale well.

DiKsa [7]

Answer:

The specification is defined downwards according to the conclusions reached.

Explanation:

Real-world instances or examples of issues that do not scale well are listed following table:

For different uses, such as solving the equation, respectively., multiplication matrices.
It still does not scales or works well to organize a wide sequence of names or numbers as the requisite measures raise as squares by around the enlargement or increment.

The Euclidean algorithm - The Euclidean algorithm provides a wonderful way to calculate the greatest common factor of 2 numbers.

Murljashka [212]

The pseudo-code of the algorithm will be:

Start

Set n1 equal to 145 and n2 equal to 87.

Divide n1 by n2 and find the remainder.

Set n1 equal to n2 and n2 equal to the remainder.

Repeat steps 2 and 3 until the remainder is equal to 0.

The greatest common factor is n1.

End

What do you mean by pseudocode?

In computer science, pseudocode is indeed a plain language description of a steps in an algorithm or similar system. Pseudocode frequently employs structural patterns of a conventional programming language, although it is designed for human interpretation rather than machine reading. It generally omits features necessary for computation of the algorithm, including such variable declarations and language-specific code. When possible, the programming language is supplemented by natural language description details or succinct mathematical notation.
