Erlang binary longest common substring

[I Gusti Ngurah Oka Prinarjaya]

Hi,

I need longest common substring erlang implementation. Please help me

I've tried https://rosettacode.org/wiki/Longest_common_subsequence#Erlang
but very very slow T_T

and i've tried binary:longest_common_prefix([<<"i love you
2020-03-28">>,<<"i love you 2020-03-01">>]) not effective / not valid

Thank you
