The quicksort is an example of a divide and conquer algorithm in that it divides the sorting problem into smaller problems by dividing the list of items to be sorted into smaller subsets. The pivot is the mechanism that is used to segment the list. Describe how the quicksort works including a discussion of the pivot, how it is selected, and why the pivot is important to the quicksort.
Answer:
The quicksort pivot is an arbitrary element within the collection that is being sorted. Using the pivot point, the collection of elements is partitioned into two smaller lists of elements. Using some logic, the smaller elements are placed left of the pivot point, and larger elements are placed to the right of the pivot point. Ideally, you would prefer you pivot point to be a median of your dataset to optimize the creation of the two sublists into a balanced state.
Cheers.
The pivot of a quicksort algorithm ought to always be the element in the middle. Some algorithms will choose the item in the center as the pivot, while others will choose the first or last element.
What is quicksort algorithm?Quicksort is a sorting method that operates in-place. It was created by British computer scientist Tony Hoare and is still a widely used sorting algorithm.
When properly implemented, it can be slightly faster than merge sort and two or three times faster than heapsort.
The quicksort pivot can be any element in the collection being sorted. The collection of elements is divided into two smaller lists of elements using the pivot point.
Smaller elements are placed to the left of the pivot point, while larger elements are placed to the right of the pivot point.
To optimize the creation of the two sub-lists into a balanced state, you would prefer your pivot point to be the median of your dataset.
Thus, this way quicksort works.

Which decimal value (base 10) is equal to the binary number 1012?
Answer:
The decimal value of 101₂² base 2 = 25 base 10
Explanation:
The number 101₂² in decimal value is found as follows;
101₂ × 101₂ = 101₂ + 0₂ + 10100₂
We note that in 101 + 10100 the resultant 2 in the hundred position will have to be converted to a zero while carrying over 1 to the thousand position to give;
101₂ + 0₂ + 10100₂ = 11001₂
Therefore;
101₂² = 11001₂
We now convert the result of the square of the base 2 number, 101², which is 11001₂ to base 10 as follows;
Therefore converting 11001₂ to base 10 gives;
11001₂= 1 × 2⁴ + 1 × 2³ + 0 × 2² + 0 × 2 ¹ + 1 × 2⁰
Which gives;
16 + 8 + 0 + 0 + 1 = 25₁₀.
The decimal value in base 10 that is equal to the binary number 101_2 is; 5
We want to convert 101_2 from binary to decimal.
To do this we will follow the procedure as follows;
(1 × 2²) + (0 × 2¹) + (1 × 2^(0))
>> (1 × 4) + (0 × 2) + (1 × 1)
>> 4 + 0 + 1
>> 5
In conclusion, the decimal value we got for the binary number 101_2 is 5
