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, ... })
