I want to write a function in c++ that does the following.

Lets say I have a string x = "ACTNCT and an integer k. I want to create all the possibile kmers from this string. So the output should be ACT,CTN,TNC,NCT if k=3. Now the problem is that for all the kmers created, I only want to print the kmers without the letter"N" in it. So the correct output should be ACT. This function should work with any size of string and any integer of k. For example, if the string is "ACTNC" and k = 5; nothing should be printed. If the string is "AACGTN" and k =3, should print AAC, ACG.

The Alorthim is the following:

for(int i = 0; i

}
