Thanks for the feedback. Here's my part 2
[: +/ [: (*@:(+/)@:(3&(({: = {.)\)) *. (#@~. ~: #)@:(2 ]\ ]) *.
-.@*@:(+/)@:(3 <:&1@#@~.\ ]))&> ]
Which is countGoodPt2 f.
countGoodPt2 lines
53
func 'has2Pair'
It has a pair of letters that occurs at least twice
ex: has2Pair 'aaaa'
ex: 1 = has2Pair 'aaa' NB. overlapping is ok here
ex: 0 = has2Pair 'aa ab'
has2Pair=: ((#@~. ~: #) @: (2]\]))
)
func 'hasNo3Consec'
It does not have 3 of the same letters consecutively
ex: 1 = hasNo3Consec 'aba '
ex: 0 = hasNo3Consec 'aaa'
ex: 0 = hasNo3Consec 'abaaa'
ex: 1 = hasNo3Consec 'abaaba'
hasNo3Consec=: -.@*@:(+/) @: (3 (<:&1@#@~.)\ ])
)
func 'has2PairNoOverlap'
It contains a pair of any two letters that appears at least twice
in the string without overlapping, like xyxy (xy) or aabcdefgaa
(aa), but not like aaa (aa, but it overlaps).
ex: has2PairNoOverlap 'xyxy'
ex: has2PairNoOverlap 'aabcdefgaa'
ex: 0 = has2PairNoOverlap 'aaa'
ex: 0 = has2PairNoOverlap 'ueihvxviirnooomi'
has2PairNoOverlap =: has2Pair *. hasNo3Consec
)
func 'hasRepeatWithLetterBetween'
It contains at least one letter which repeats with exactly one letter
between them, like xyx, abcdefeghi (efe), or even aaa.
ex: hasRepeatWithLetterBetween 'xyxy'
hasRepeatWithLetterBetween =: *@:(+/) @: (3&(({: = {.)\))
)
func 'countGoodPt2'
counts how many lines match the criteria in p2
ex: 1 = countGoodPt2 ('aabcdefgaa';'xyxy')
countGoodPt2 =: [: +/ ([: (hasRepeatWithLetterBetween *.
has2PairNoOverlap) every ])
)
