From my experience of analyzing various datasets, I have noted down few notes regarding the workflow for datascience that I recommend.
If you want to import data from excel files in R program, it is quite simple and easy. We will look at few code examples of how to do this.
Heap sort algorithm is very efficient and costs O(log(n)) time complexity. Here is an implementation in Python.
Bubble sort algorithm costs 'O(n*n)' time complexity. Here is an implementation in Python.
Quick sort algorithm also costs O(n\*n) time complexity. It uses a divide and conquer approach - it keeps partitioning and sorting those partitions until done. Here is an implementation in Python.
