• The pre-processing time of Rabin and Karp Algorithm is Theta(m).
• The for loop in the pre-processing algorithm runs for m (the length of the pattern) times, hence the pre-processing time is Theta(m).
• This is the time complexity of the pre-processing phase of the Karp-Rabin algorithm.

Explanation

A data pipeline is a series of processes that extract data from multiple sources, transform the data into a standardized format, and load it into a target system for analysis.

The primary purpose of a data pipeline in data modeling is to prepare and transform data for analysis, making it possible to:

• Extract data from various sources
• Clean and preprocess the data
• Transform the data into a format suitable for analysis
• Load the data into a data warehouse or analytics platform
