Alphabetical sort of characters within a string.

[bplus]

@euklides yes very short but if you knew the word doesn't repeat letters or didn't care, it could be useful

+1 @Circlotron thanks for bringing up this topic, my anacode$ has been improved by it i am getting you out of 0 ;-)) yes every little improvement to code is the right mindset IMHO. you can be obsessed by worse things

[bplus]

looks like peteCode2$() is fastest sorter of letters in a word. anacode2$ was worse using mid$ = trick to save time, did improve orig 26 digit version of anaCode$ to be used in apps that look for words in the letters of bigger word.

i honestly thought it wouldn't work but it did.

...

i honestly thought it wouldn't work but it did.

Bada Bing!! You're welcome, oh ye of little faith.

Now your code is beginning to look more like the one which I shared from the beginning for you. https://qb64phoenix.com/forum/showthread...3#pid24733

[Circlotron]

What I have managed to do for my anagram finder to speed things up a whole lot is to have a the big word list, also a number of smaller files, each one containing words of equal length, also matching files containing L-R sorted versions of the same words in the same order. These files are named 3,4,5 etc and 3S,4S,5S etc. When a word from the main file is read, the length of that word opens the corresponding word length file and the matching sorted word file. These are a lot shorter than the big file, so a full scan of these is way quicker than a full length file. What's more, both the equal length word file and it's corresponding sorted file are read together, so when a sorted match is found, the corresponding anagram is read directly from the equal length file. The point is, the words being tested don't have to be sorted repeatedly on the fly, this is already done and stored in the sorted file. Edit -> These changes have sped things up by a factor of 9.2 times.

+1 ok this has been quite an adventure past couple days

i would probably have been onto it quicker had you shared the file you were using with code in zip but still a hard won lesson will be likely remembered better/longer.

i wonder if that trick will help the other version of anaCode with all the letter counts or PeteCode ?

i did the Rosetta Code challenge for anagrams about 7 years ago, steve too so don't remember exactly what was done then... i'd be inclinded to write an 2 word array with the anaCode for the first word then the word for second, then sort it by first word key, so all like anacodes are bunched together and just read down the array looking for the biggest bunch.

ah altAnaCode$ now edges out PeteCode2$ barely

Code: (Select All)

Function altAnaCode$ (wrd$) ' anaCode$ converts word to an Anagram pattern
    Dim As Integer L(65 To 90), i, p
    Dim t$(65 To 90)
    Dim rtn$, w$
    w$ = UCase$(wrd$) ' don't assume all caps  as expected
    For i = 1 To Len(w$)
        p = Asc(w$, i) ' A=1, B=2...
        L(p) = L(p) + 1
    Next
    For i = 65 To 90
        t$(i) = LTrim$(Str$(L(i)))
    Next
    altAnaCode$ = bind$(t$())
End Function

can petecode2$ also benefit from bind$ trick? it seems like it will be going backwards?

    Dim t$(1 To Len(la$))
    a$ = UCase$(la$)

        seed% = InStr(a$, Chr$(i%))
        While seed%
            j% = j% + 1
            t$(j%) = Chr$(i%)
            seed% = InStr(seed% + 1, a$, Chr$(i%))
        Wend
    Next
    petecode3$ = bind$(t$())
End Function

petecode2$ was already using mid$ trick just not en mass as bind$() does it. you'd think the extra steps to save all the strings into an array to bind and extra call to bind would take longer, but no!

oh got to clean code and run tests with browser off...
