Which dynamic programming technique is used to solve the problem of finding the minimum edit distance between two strings?
Step 1: Understand the problem - The minimum edit distance is the number of operations needed to change one string into another.
Step 2: Identify the operations - The common operations are insertion, deletion, and substitution of characters.
Step 3: Create a table - Set up a 2D table where rows represent characters of the first string and columns represent characters of the second string.
Step 4: Initialize the table - Fill the first row and first column with numbers representing the cost of converting an empty string to the other string.
Step 5: Fill the table - For each cell in the table, calculate the minimum cost based on the three operations (insert, delete, substitute) and fill the table accordingly.
Step 6: Read the result - The value in the bottom-right cell of the table will give you the minimum edit distance between the two strings.
