    Default All possible combinations of a 1D array

    Hi everyone, I'm Gabriel from Greece,

    I have a little problem with a part of code I'm trying to write. Actually it's a part from a bigger code.
    I want to do this:

    Lets say that I have a String array: projects{"A", "B", "C", ...}. The size of the array can be changed so the code should worn for n elements.

    I want this output:

    A
    B
    C
    AB
    AC
    BC
    ABC
    ...

    Note that AB is equal to BA, AC=CA, ...

    Thanks for your time for reading this and I would really appreciate if someone could write me the code, because I'm trying to write it for a few days now and I couldn't do anything. Thanks again.

    wikipedia combinations, get an idea of the maths behind it. Then limit the size of the array to one chunk then 2 chunks etc etc

    Combination Generator
    See, I am not big fan of copying especially programming. You copy everything, fail in everything, but be loyal with programming and you will rock. The above should be some code, which I suggest you take a look, once you spend some time yourself. Also your problem is little bit more than generating combinations. (basically combinations - palindromes)
