In this section, we will go through some basic around data science and software engineering. During a technical interview, you may be asked to code the algorithms by scratch, or some data science libraries in front of the interviewers. We will explain the concepts, features and code behind.
Sorting algorithm is an algorithm that puts elements of a list in a certain order. In our examples, we sort the elements by ascending order.
Searching algorithm is an algorithm that search the target element from the elements in a list and return its location.
Pandas is a powerful and popular open-source library for data manipulation and analysis. It provides data structures and functions specifically designed to work with structured data, making it a go-to tool for data science, analytics, and machine learning tasks.
They are considered as the fundamentals in data structure and widely applicable in our daily life, for example searching keywords in a website, sorting score in a spreadsheet. From an interview perspective, it is an effective way to test your coding and logical skills without tapping into any complex algorithms. It is strongly recommended to read below sections and try to code yourself before any interviews !!
