Answer:
When the element is not found we return -1.
Explanation:
When we use binary search we use BinarySearch() method of an array or list type when the element is found we return the index of the element if found if the element is not found we return -1.
We can decode this value since it is less than 0 and the indexing of arrays and lists starts with 0 upto the size-1.So -1 index is not present in the array or list.We have to check if the index is < 0 then the element is not present in the array or list.
for ex:-
if(index<0)
{
System.out.println("Element is not present in the array");
}
The answer is a Mesh topology. This method connects every device to each other device in the network. A wired full-mesh topology is not as common as it is impractical and highly expensive. A partial mesh topology offers redundancy if one of the connections goes down and usually uses a connecting medium such as a router to eliminate cables and expensive PCI NIC's.
Answer:
rv = "hello"
num_chars = len(rv)
print(num_chars)
Explanation:
*The code is in Python.
Initialize the string rv, in this example I set it to "hello"
Use the len() method to get the number of characters in the rv and set it to the num_chars
Print the num_chars
Note that the result will be 5 in this case, because <em>hello</em> consists of five characters
Answer:
Spreadsheet
Explanation:
Spreadsheet applications like Microsoft Excel, Google Sheet, etc. makes the task of managing and presenting the mathematical data quite easy and perfect. It consists of rows and columns, and in each cell, we can apply a set of formulas. Its a great data mining tool as well, where the unprocessed data is cleaned, to form a piece of information at various levels, and fed to top management. It helps in all sorts of analysis, and like statistical analysis. And it supports data visualization as well. which makes the analysis even more fruitful and easy. However, its drawback is, the set of variables cannot be more than 3. And that is where the software like Microsoft Power BI and tableau comes into the picture. And they support spreadsheets as well as various other formats.
