in thread How do I remove the duplicates from the array?

I do not understand the line $sort[-1]>$sort[0] ? $sort[-1] : undef. What if the values are 7, 8, 8? How will it discard the whole thing? I know the OPs spec is rather cryptic but my understanding was, that the values are to be blanked out if the max occurs more than once.

    hmm ... ok my understanding was to discard if all are maximum, see (3,3,3)

    But your definition is indeed closer to the naming highlander, maybe peak was better.

    edit

    For highlander compare with [-2] if there are more than 2 elements.

    BTW: "cryptic" is an euphemism for incompetent ... if you can't express such a problem in words you don't deserve being called a programmer.

      Unless the OP clarifies, it is probably not a meaningful discussion...

        well ... as usual, see my BTW in the edit! =)

        I'm trying to avoid such threads, but I thought that abstracting to functions like highlander or peak might be useful for

        • clarification
        • documentation
        • reusability
