Jerry's 2017-year 51 vacation: the ABAP implementation of 8 classic sorting algorithms

April 29, 2017 to 1st, Labor Day, three days of small holiday.
At home, a small holiday is often the case:

However, I was jokingly called "Village" (German rural) Walldorf business trip and live in Wiesloch, where the 51 small holiday can hear birds, insects, and the sound of the wind, there is nothing else.
Don't talk about pedestrians on the street, even the cars are very few.

If a person in Chengdu accustomed to lively life, to this country place to estimate will feel bored. At that time, some colleagues in China suggested that I take a long vacation to other places in Germany, but as a 30-year veteran otaku, a person to go out is not my style.

51 Before the holiday, a S/4 Hana product manager sitting across from me, more than 30-year-old Iranian, looks pretty and asks me before work: "Any plan for the coming holiday?" I replied: "Stay at home, continue PR Ogramming ". Product manager Zhang Big Mouth to a sentence: "You are a nerd!."

In fact, I really want to see this picture of the Chinese programmer's life.

To the next, online about the implementation of various languages of the classic sorting algorithm of a plethora of posts, but the lack of ABAP version of the implementation, so I wrote a:

From the posting time to see exactly 51 small vacation. It took me a day to write these eight pieces of code, mostly to debug and fix bugs.
This is finally a complete:

A simple test, sure enough, is the ABAP sort keyword, and the performance is higher in kernel with C.

There is a netizen to me this kind of behavior is very puzzling:

Another netizen, look at the tone is also otaku + program ape, jump to help me to answer: the effect is, in the spare time programming can not bring any purpose, happy is good.
Yes, program apes are sometimes so capricious.
