Introduction to Edit Distance

Edit distance is a concept in string manipulation that measures the similarity between two strings. It calculates the minimum number of operations required to transform one string into another. These operations include:

  • Insertion: Adding a character to a string
  • Deletion: Removing a character from a string
  • Substitution: Replacing a character in a string

The edit distance is widely used in various applications, such as spell checking, DNA sequencing, and natural language processing. By understanding edit distance, we can develop efficient algorithms for solving string-related problems.
