A Python module for finding arithmetic sequences for a given sequence.
Just enter a list and get back all arithmetic sequences from it! 🚀
Module returns a list of lists that contain arithmetic sequences found in the entered list
arithmeticSequences(A,n) returns a list of lists of all arithmetic sequences from list A with common difference n or all common differences if n = 0. This includes subsequences of existing sequences.
An arithmetic sequence is valid only if it has more then 2 items.
distArSeq(A,n) returns a list of lists of distinct arithmetic sequences from list A with common difference n or all common differences if n = 0.
distArSeq(A,n) returns a list that has no arithmetic sequences that are a subsequence of an existing sequence.
An arithmetic sequence is valid only if it has more then 2 items.
>>> import arithmeticSequence as ASE
>>> arSeq = [61,10,11,30,21,20,40,41,50,60,1,70]
>>> ASE.distArSeq(arSeq)
[[1, 11, 21], [1, 21, 41, 61], [10, 20, 30, 40, 50, 60, 70], [10, 30, 50, 70], [10, 40, 70], [20, 40, 60]]
>>> ASE.distArSeq(arSeq,20)
[[1, 21, 41, 61], [10, 30, 50, 70], [20, 40, 60]]
>>> arSeq = [2,10,17,24,31,38,45,52,60]
>>> ASE.distArSeq(arSeq)
[[2, 31, 60], [10, 17, 24, 31, 38, 45, 52], [10, 24, 38, 52], [10, 31, 52], [17, 31, 45]]
>>> ASE.distArSeq(arSeq,7)
[[10, 17, 24, 31, 38, 45, 52]]
>>> ASE.distArSeq(arSeq,11)
[]
>>> arSeq = [1,10,30,40,80,110]
>>> ASE.distArSeq(arSeq)
