# Method Array.diff_dyn_longest_sequence()

Method diff_dyn_longest_sequence

  ``array`(`int`) diff_dyn_longest_sequence(`array` `a`, `array` `b`)`

Description

  Gives the longest sequence of indices in `b` that have corresponding values in the same order in `a`.

  This function performs the same operation as diff_longest_sequence(), but uses a different algorithm, which in some rare cases might be faster (usually it's slower though).
