For years, the residents of DMOJistan have been besieged by a single question - what does AK stand for?

Well, it's time for you to find out! Please implement the following function:

string f()

This function should return the phrase that AK stands for. Please make sure that you format the phrase properly, as we will be using an identical checker to evaluate the correctness of your submission. You will never need to include newlines in your answer. If you need to use a space in your answer, you will never need to use two consecutive spaces.

If you don't know what AK stands for, here's a hint: the string you return should have length 8. It contains exactly two words comprising seven letters, with the first word starting with A and the second word starting with K.

As with all problems in this contest, you will only be permitted to submit your solutions in C++. We guarantee that contestants with no experience in C++ will not be handicapped significantly in spite of this.
