can someone simplify java code - for (int x=6; x<x*x;--x) { System.out.println(x):

Question

can someone simplify it -
for (int x=6; x<x*x;--x) {
System.out.println(x):

Answer 1

x < x*x is true to all the integers except {-1,0,1}, if you start on 6 you will always stop on 1, so the code will print {6 5 4 3 2}. One way you can do that and it's to do:

for (int x= 6; x > 1; x--) System.out.println(x);

Note: Assintotically speaking both are the same, if you are trying to find all the integers below 7 that are less then their squares, your version is better since it's easier to understand. Now, if you want to print only 6 until 2 your version is hard to understand so to keep ir simple you use the one I proposed.

Idk if I could answer your question, but good coding for you!

Answer 2

Where did you get the code, Challenges?
x<x*x is tricky as Tomás explained you can also print that to see :)

Answer 3

Yeah i got this code from challenge itself

Answer 4

Tomás there should be x--

zemiak Yes, you're right, thanks. I already fixed it.
