How can someone prove they are an expert at using the minimum edit distance algorithm to measure the separation between two texts and align them correctly using Backtrace?

To demonstrate expertise in using the minimum edit distance algorithm to measure the separation between two texts and align them correctly using backtrace, an individual can showcase their proficiency through the following methods:

Understanding of the Algorithm:
Explain the theoretical foundation of the minimum edit distance algorithm, including its components (insertion, deletion, substitution), dynamic programming approach, and how it calculates the minimum number of operations to transform one text into another.
Implementation Skills:
Showcase the ability to implement the minimum edit distance algorithm in a programming language of choice, such as Python, Java, or C++. Provide clean and efficient code that accurately computes the edit distance between two texts.
Handling Textual Data:
Demonstrate expertise in processing textual data by preprocessing and tokenizing the input texts. Handle special cases such as handling whitespace, punctuation, and case sensitivity appropriately.
