# Method Array.greedy_diff()

Method greedy_diff

  `array(array(array)) greedy_diff(array from, array to)`

Description

  Like Array.diff , but tries to generate bigger continuous chunks of the differences, instead of maximizing the number of difference chunks. More specifically, greedy_diff optimizes the cases where Array.diff returns `({ ..., A, Z, B, ({}), C, ... })` `({ ..., A, X, B, Y+B, C, ... })` into the somewhat shorter diff arrays `({ ..., A, Z, B+C, ... })` `({ ..., A, X+B+Y, B+C, ... })`
