longestCommonSubsequence return wrong result

[JauSingSing]

var suffixArray = new GeneralizedSuffixArray([
  [1,2,3,4],
  [2,3,4],
  [1,2,3,4]
])
suffixArray.longestCommonSubsequence()
>>> [1,2,3,4]

expect [2, 3, 4]

Hello @JauSingSing, you are right there is something fishy there. I think I need to rewrite this code to fix those kind of cases and optimize it altogether, I wrote this quite a long time ago.
