Are all the examples OK here?

#1

In the first example 1 char is skipped in the output for K=2:

Input: "mmpp", K=2
Output: "mpmp" or "pmpm"

But in the next example 3 or more actual chars are skipped:

Input: "Programming", K=3
Output: "rgmPrgmiano" or "gmringmrPoa"

So my question is:
is the next answer for the last example is a valid one?:
“rgmrgmPiano”

Thanks.

@Design_Gurus I also don’t get what “K distance apart” exactly means here. In the first example, as @Pavlo_Koshla mentioned, you are saying that K=2 but the output shows that chars go through one.
Could you please add some clarification to this problem description?

#3

“K distance apart” means that the character can reappear after this distance. For example, for K=2, if a character is at index “5” it can come again at index “7” or higher.
