Answer:

Hi! I suppose that no matter the programming language that you need the algorithm, so I will do in pseudo-code.

 

myArray [int] = [1,2,3,4,5,"Hello","World"];

int i = 5;

int j = 2;

// Save the previous value before the swap

aux1 = myArray[i];

aux2 = myArray[j];

// Swap i & j

myArray[j] = aux1;

myArray[i] = aux2;

print(myArray)

// Out : myArray = [1,2,"Hello",4,5,3,"World"]  

Explanation:

The trick is to save in two variables the previous value of the two position before change the array, just like that you can change the array and make the swap without lost the values.

I hope it's help you.

Explanation:

On October 31, around twelve o'clock at night, the lights were dull. It was Siberian cold and I was walking painfully under the whitish lighting of a lamppost and the retro neon lights of a convenience store in a neighborhood that was buzzing when I went to buy meat. buildings, grayish in this half-light, crumbled under the weight of sleep, while the neighborhood was still open. Its decoration was particularly macabre in tone: synthetic but very sticky spider webs adorned the porches of the terraces, pumpkin ornaments are exhibited like works of art, ... Some pushed the macabre by hanging mannequins made up in corpses. At the entrance to the neighborhood, I found the body of its owner stabbed. Frozen in place, I wondered what else awaits me. My heart was pounding, feeling a shiver of anguish. When I was removing the phone from my pocket to call my police friends, my hands were clenched in fear. An investigation was carried out to find out the causes of death. Also, I went with them so they take my words. Hopefully the murderer will be arrested to put an end to this sybilinous crime.

A Red Black Tree is a type of self-balancing(BST) in this tree ,each node is red or black colored. The red black tree meets all the properties of the binary search tree, but some additional properties have been added to a Red Black Tree.

A Red-Black tree's height is O(Logn) where (n is the tree's amount of nodes).

In a red-black tree with black height k

The maximum number of internal nodes is 2^{2k} -1.

The smallest possible number is 2^{k} -1.

A calculator is not a computer because​

\huge\fbox\red{❥answer}

By definition a computer is an electronic device used to store and compute data. So, by definition a calculator stores and interprets data/numbers, and that makes it a computer. However, a computer can also use programs, and manipulate stored data to complete those programs.

hope it helps!! :D
