Question can't solve it

Question

system asks for two numbers. i need to print the numbers between them from the small to the big and reverse (big to small) for ex: 123321

Answer 1

you can create 2 loops.

a = 1
b = 3

for(int i = a; i<=b; i++)
Console.Write(i);
for(int i = b; i<=a; i--)
Console.Write(i);

Answer 2

second loop condition is wrong. it should be like I>=a;

Answer 3

hi
