Let G = (V, E) be an undirected graph. Design algorithms for the following (in each
case discuss the complexity of your algorithm):
(a) Assume G contains only one cycle. Direct the edges s.t. for each u, indegree(u) [tex]\leq[/tex] 1.
(b) Determine whether it is possible to direct the edges of G s.t. for each u, indegree(u) [tex]\geq[/tex] 1.
If it is possible, your algorithm should provide a way to do so.
(c) Let S be a subset of edges s.t. every cycle of G has at least one edge in S. Find a
minimum size subset S.

which data representation system is based on the digits 0-9 and is mostly easily interpreted In real wrold situations​

Answers

Answer:

Hexadecimal  data representation system is based on the digits 0-9 and is mostly easily interpreted In real word situations​ .

Explanation:

Hexadecimal manages sixteen different figures: most often the numbers 0–9 to describe values zero to nine, and (A–F) to describe values ten to fifteen. The modern hexadecimal system was first launched into the domain of computing by IBM in 1963. An older description, with 0-9 and u-z, was practiced in 1956 by the Bendix G-15 computer.

Write a program that takes a String containing a text using the method signature

String useProperGrammar(String text)
Your method should replace the word ‘2’ with ‘to’ and return the updated text.

For example,

useProperGrammar("can you go 2 the store?")
should return

"can you go to the store?"
This method should also print out the number of grammatical errors that were fixed.

For example, for useProperGrammar("back 2 back 2 back"), the method would also print:

Fixed 2 grammatical errors:
In the main method, ask the user to input a String, and print the results of useProperGrammar using the user input.

Answers

import java.util.*;

public class MyClass {

   public static String useProperGrammar(String message){

       String newMessage = "";

       int count = 0;

       for (int i = 0; i < message.length(); i++){

           if(message.charAt(i) == '2'){

               newMessage = newMessage + "to";

               count ++;

           

           }

           else{

               newMessage = newMessage + message.charAt(i);

           }

       

       }

       System.out.println("Fixed "+count+" grammatical error(s):");

       return newMessage;

   }

   public static void main(String args[]) {

     Scanner scan = new Scanner(System.in);

     System.out.println("Enter a string: ");

     String text = scan.nextLine();

     System.out.println(useProperGrammar(text));

   }

}

Suppose a webpage contains a single text field. We want to make the page such that a user can immediately start typing in the text field without clicking on it. What is correct way using?
1. .
2. .
3. .
4. Can't be done with only HTML5, need help of Javascript or something else.

Answers

Answer:

The answer is "Option 2".

Explanation:

In HTML5, text inputs use an autofocus attribute, which, when the page is loaded, uses a template to concentrate primarily on text fields. This attribute is a Boolean property that represents the HTML autofocus attribute, showing if the related <select> element will receive an output focus whenever the page loads if it is overruled by the user. An only form-associated entity can have this property specified in a text.

Your organization uses a federated identity provider to login to your Oracle Cloud Infrastructure (OCI) environment. As a developer, you are writing a script to automate some operation and want to use OCI CLI to do that. Your security team doesn't allow storing private keys on local machines. How can you authenticate with OCI CLI?

Answers

Answer:

Run OCI session authenticate and provide your credentials

Explanation:

The OCI CLI when in combination with a shell script can be fastly used in the creation of shareable scripts. It uses API keys, private and public scheme as it's default authentication. The command to use is the oci set up keys, to create these keys. Since you cannot store private keys, you run OCI authentication and then you give your credentials
