"For centuries, left-handers have suffered unfair discrimination in a world designed for right-handers."
Santrock, John W. (2008). Motor, Sensory, and Perceptual Development.
"Most humans (say 70 percent to 95 percent) are right-handed, a minority (say 5 percent to 30 percent)
are left-handed, and an indeterminate number of people are probably best described as ambidextrous."

One of the robots is charged with a simple task:
to join a sequence of strings into one sentence to produce instructions
on how to get around the ship.
But this robot is left-handed and has a tendency to joke around and confuse its right-handed friends.
You are given a sequence of strings.
You should join these strings into a chunk of text where the initial strings are separated by commas.
As a joke on the right handed robots, you should replace all cases of the words "right" with the word "left",
even if it's a part of another word. All strings are given in lowercase.
A sequence of strings.
The text as a comma-separated string.
left_join(("left", "right", "left", "stop")) == "left,left,left,stop"
left_join(("bright aright", "ok")) == "bleft aleft,ok"
left_join(("brightness wright",)) == "bleftness wleft"
left_join(("enough", "jokes")) == "enough,jokes"
How it is used:
This is a simple example of operations using strings and sequences.
