  Given two strings word1 and word2, return the minimum number of operations required to convert word1 to word2.
  You have the following three operations permitted on a word:
  Insert a character
  Delete a character
  Replace a character
  
  Example 1:
    Input: word1 = "horse", word2 = "ros"
    Output: 3
    Explanation:
    horse -> rorse (replace 'h' with 'r')
    rorse -> rose (remove 'r')
    rose -> ros (remove 'e')
  
  Example 2:
    Input: word1 = "intention", word2 = "execution"
    Output: 5
    Explanation:
    intention -> inention (remove 't')
    inention -> enention (replace 'i' with 'e')
    enention -> exention (replace 'n' with 'x')
    exention -> exection (replace 'n' with 'c')
    exection -> execution (insert 'u')

  var minDistance = function(word1, word2) {
  
  };
  console.log('hello')
