no problem guys, I won't dare to bore no programming elites here. My deeply excuses.

is it possible to ask someone suggestion for my code when I flag it as spoiler? Is there a way of obtaining help here or not? If I post a code shall it be spoilred so that is unvisible? wtf...?

thanks again, yes I've looked into the sorting of strings, but it looks it's not the case for this problem, sorting characters is an inner scale problem instead of sorting a string which contains digits...for me basically this problem is unsolvable, but I am used to think this way, always ;) programming equals to frustration and if sometimes I success it's the exemption, not the ordinary . Anyway thank you again, I appreciate your help, I'll see what else can find and try...

thank you for the notice. Apart the spoiler, any comment helpwise to my question?

Ok now I got it...I admit my ignorance and the very seldom use of this kind of notation with three dots "...". Now I understand it is the "Arbitrary Number of Arguments"...

Please can someone help me understanding this one? How can I put as an argument an empty array of strings since the dimension can't be changed at the end? I am not able to declare an empty array of strings which will be populated by names after. The dimension is zero and of course remains zero... Frustration mode On.
