# Order Integers From Ascending as Well As Descending Order [closed]

I am working through a worksheet of for loops in c# and have come across this problem,

"Write a program to request an integer n from 1 to 9 and print a line of output consisting of ascending digits from 1 to n followed by descending digits from
n – 1 to 1. For example, if n = 5, print the line 12345432".

This is my code so far

        int n;
Console.Write("Enter A Number From 1 To 9: ");
if (n > 9 || n < 0)
{
Console.Write("Enter A Valid Number: ");
}

for (int i = 1; i<=n; ++i)
{
Console.Write(i);

}
for (int j = n; j >= 1; --j)
{
Console.Write(j);
}


The issue I am having is on my descending output it repeats the original user input value, for instance; n=5

output = 1234554321

I know why this is, it's because I have made j == n, however I cannot seem to think of any other way to achieve the second part of the question where I need to output the descending digits. Any help or suggestions is greatly appreciated!

• assign to a string the output of the first for loop. Then do the same for the second for loop. Then output after both for loops. FYI if it's supposed to be from 1-9 then your if condition checking for less then 0 needs to be <=0 to ensure you get 1-9, because right now you are going to allow 0. – Caperneoignis Feb 11 at 19:59
• so string value =''; then value += i.toString(); in both loops – Caperneoignis Feb 11 at 20:02
