Complete the method/function so that it converts dash/underscore delimited words into camel casing. The first word within the ou

nata0808 [166]

Answer:

I am writing a Python program. Let me know if you want the program in some other programming language.

def toCamelCase(str):

string = str.replace("-", " ").replace("_", " ")

string = string.split()

if len(str) == 0:

return str

return string[0] + ''.join(i.capitalize() for i in string[1:])

print(toCamelCase("the-stealth-warrior"))

Explanation:

I will explain the code line by line. First line is the definition of toCamelCase() method with str as an argument. str is basically a string of characters that is to be converted to camel casing in this method.

string = str.replace("-", " ").replace("_", " ") . This statement means the underscore or dash in the entire are removed. After removing the dash and underscore in the string (str), the rest of the string is stored in string variable.

Next the string = string.split() uses split() method that splits or breaks the rest of the string in string variable to a list of all words in this variable.

if len(str) == 0 means if the length of the input string is 0 then return str as it is.

If the length of the str string is not 0 then return string[0] + ''.join(i.capitalize() for i in string[1:]) will execute. Lets take an example of a str to show the working of this statement.

Lets say we have str = "the-stealth-warrior". Now after removal of dash in by replace() method the value stored in string variable becomes the stealth warrior. Now the split() method splits this string into list of three words the, stealth, warrior.

Next return string[0] + ''.join(i.capitalize() for i in string[1:]) has string[0] which is the word. Here join() method is used to join all the items or words in the string together.

Now i variable moves through the string from index 1 and onward and keeps capitalizing the first character of the list of every word present in string variable from that index position to the end. capitalize() method is used for this purpose.

So this means first each first character of each word in the string starting from index position 1 to the end of the string is capitalized and then all the items/words in string are joined by join() method. This means the S of stealth and W of warrior are capitalized and joined as StealthWarrior and added to string[0] = the which returns theStealthWarrior in the output.

In your own words, describe the structure and function of both the stack and queue data structure and discuss how they are diffe

Kobotan [32]

Answer:

Following are the answer to this question:

Explanation:

Stack:

The stack data structure is used to create method, parsing, analysis of expression, and tracking. This data type uses the LIFO system, which stands from the Last In First Out. This data structure operates on the top side. In this data structure, it performs two methods, that are "push() and pop()" method and the time complexity of the stack data structure O(1).

Example of Stack:

import java.util.*;//import package

public class Main //defining class Main

{

public static void main (String[] ag)//defining main method

{

ArrayDeque<Character> stack = new ArrayDeque<Character>();//creating Character array ArrayDeque

stack.push('A'); //add value in stack

stack.push('B');//add value in stack

stack.push('B'); //add value in stack

System.out.println("First Insert:"+stack); //print value stack.pop();//remove value from stack

System.out.println("After removing element: "+stack); //print value stack.push('B'); //add value in stack

stack.pop();//remove value from stack

System.out.println("final value: "+stack); //print value

}

Output:

First Insert:[B, B, A]

After removing element: [B, A]

final value: [B, A]

Queue:

The queue data structure is an abstract type, it is similar to the stacks data structure. It is open at both ends when opposed to lines. It follows the FIFO method, which stands for the First-In-First-Out method, At one end data is inserted and at the other end, it deletes the data and the time complexity of the queue data structure O(1).

Example of Queue:

import java.util.*;//import package

public class Main//defining a class queue

{

public static void main(String[] ars)//defining main method

{

LinkedList<Integer> que= new LinkedList<Integer>();//defining integer array LinkedList

for (int i = 0; i < 5; i++)//defining fo loop to add value in queue

{

que.add(i); //use add method to insert value

}

System.out.println("Queue value: "+ que); //print queue value

int remove= que.remove(); //remove value from the queue System.out.println("after removing value from queue: "+ remove);//removing element from queue

System.out.println(que); //after removing the element print value

}

Output:

Queue value: [0, 1, 2, 3, 4]

after removing value from queue: 0

[1, 2, 3, 4]

spayn [35]

We use analog and digital signals in our everyday lives with the radio, the cell phone and with our own computers. our computers and our cell phones are all digital now but radio's are still considered analog. Radio telescopes explore space by using radio waves and signals to almost like scan space and collect data like a sonar in a submarine.
