Algorithms

Algorithms are a type of technology used in multiple fields of study that dictate or alter streams of information (in this case we will most be referring to computer science). The code/pseuocode presented on here will be written in Python (### syntax in the code represents comments made in Python code).

Case Uses For Implementing Algorithms (Engineering and Computer Science) :

Common Computer Science Algorithms

Algorithms used in Computer Science are developed and implemented to alter the way data moves in network somehow ( the network representing the collection of data used to create a program/system )

The most common present:

Insertion Sort

---

Insertion Sort (sorting algorithm for small number of elements): This Algorithm rearranges a disordered list of integers and rearranges them in natural order. This algorithm is typically used for small array of elements.

Sample Input : [ 8, 3, 9, 0, 2, 7, 4, 5 ] Sample Output : [ 0, 2, 3, 4, 5, 7, 8, 9 ]

Example Python Code

Python Insertion Sort Example 1

def insertionSort(alist):
  for index in range(1,len(alist)):

    currentvalue = alist[index]
    position = index

    while position>0 and alist[position-1]>currentvalue: #print integers in natural order[-1] less than the previous number
      alist[position]=alist[position-1]
      position = position-1

    alist[position]=currentvalue

alist = [54,26,93,17,77,31,44,55,20]  ### this is the array of integers that will be sorted in natural order 0-infinity
insertionSort(alist)
print(alist)

Python Insertion Sort Example 2

function insertionSort(array A)
    for i from 1 to length[A]-1 do
        value := A[i] 
        j := i-1
        while j >= 0 and A[j] > value do
            A[j+1] := A[j]
            j := j-1
        done
        A[j+1] = value
    done


### Syntax states to apply InsertionSort to Array of Integers named A. from 1 to any number -1 
###from previous number in array, print in natural order.
