Compare Text activity implements [Myer's diff algorithm](https://neil.fraser.name/writing/diff/myers.pdf) which is generally considered to be the best general-purpose diff.

  

**Example:**

  

Input:

  

*   Text1: "Hello World."
*   Text2 "Goodbye World."

  

Output:

*   List&lt;KeyValuePair&gt; of differences is computed which describe the transformation of text1 into text2.
*   The first element specifies if it is an insertion (1), a deletion (-1) or an equality (0). The second element specifies the affected text.
*   Therefore the result for the above Text1 and Text2 is: \[(DELETE, "Hello"), (INSERT, "Goodbye"), (EQUAL, " World.")\]

Compare two blocks of plain text and efficiently return a list of differences.
