Write a program in python that: 1. Implement the minimum edit distance algorithm, using Levenshtein distance with cost of 1 for insertions or deletions, 2 for substitutions. Given any pair of words, you should output the following four pieces of information: (a) Minimum edit distance (b) Distance matrix (c) Pointer matrix (d) Alignment2. To test the correctness of your algorithm, you may use input words intention and execution.
