DIY: Edit Distance

Explore how to determine the minimum edit distance between two strings by implementing a function that calculates the fewest insertions, deletions, and replacements to transform one string into another. This lesson helps improve problem-solving skills useful in coding interviews and computational biology contexts.

Problem statement

Given two strings, str1 and str2, you have to return the minimum number of edit operations that are required to convert str1 to str2.
