How do you print out words in reverse in Perl If you put in words one two three it should print three two one?

You need to do your own syntax, since PERL was a while ago for me. In short, you can go study the two concepts FIFO and LIFO (FY-fo and LY-fo). These are queue management methods, the first being "first in, first out - FIFO", the second being "last in, first out - LIFO". LIFO is what you want, and there are several ways to do it.
A nice way using elementary data types (which will get you some good practice) is to loop through the input string(s), and store them in an array of strings. Count the loop upwards using a counter in sync with the array index [0 ... x]. When you finish processing all the input strings, write another loop that starts outputting the strings with the high counter value, and decrements by 1 each loop [x down to 0]. Make the counter/index = 0 be your last pass, and exit.
You can build a single string using concatenation and output that, or output a single word each time you loop. To be flexible, you will want to dynamically allocate memory to the array(s), otherwise, if you declare a static Array[100], then the first time you encounter input over 100 words long, your code tanks.

I have an idea to paint my bedroom wall and while wet stick newspaper on it and take it off leaving words on the wall How can you print newspaper words on a bedroom wall without being backwords?
The idea is good, but I'm not sure the technique will work. News print ink is such that it will lift fairly easily, but as you pointed out, it is reversed when you remove the paper. You could use your computer to reverse the image, and print it in black and white. You can also adjust your font size while you are at it.
