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.
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 (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 ]
Python Code --- def insertionSort(alist):
- for index in range(1,len(alist)):
::currentvalue = alist[index] ::position = index
- while position>0 and alist[position-1]>currentvalue:
- alist[position]=alist[position-1]
- position = position-1
- while position>0 and alist[position-1]>currentvalue:
- alist[position]=currentvalue
alist = [54,26,93,17,77,31,44,55,20] insertionSort(alist) print(alist)
