Thread: Need help with nested for loops to print the following number pattern

Well, here's the deal: Assuming this is the desired output of a program, every number will be printed because an instruction in the program prints it.

Furthermore...

Every comma will be printed because an instruction in the program prints it.

So...

If you don't want a commas at the end of the last integer on the lines, then don't put instructions in the program to print them.

If we could see your code, maybe we could understand why it prints stuff that you don't want (assuming that's the kind of help you would like).



Cheers!

In a loop, just create a check if it's 1 don't follow it with comma, else keep printing the number following comma.
Remember, if it's 1, if it's other than 1, i hope you can make the logic.

Ops yeah it's first ascending then descending. Yeah you are right jps.
Yeah then that would become for getting the size if let's assume (i is dealing in the loop) i has the value which is almost gonna end up the loop after the iteration, don't put comma otherwise continue with the other statements.
