Palindromic number

Question

In order to find out if a number is a palindromic number, the input needs to be spilt up and reversed.
How do you split it?
Thanks

Answer 1

get last digit (using %) and divide by 10 until number reach 0 ^^

Answer 2

You can also try this as well...
1.Convert `n` in to string using to_string(int) function...
2.scan the string from beginning and end, up to middle..and check that if corresponding elements are equal or not..
If yes , return true
Otherwise false

Answer 3

by converse operation (assuming you want to join them in reverse order):

initialize a variable to zero (or use the previous one)
for each digits, multiply the variable by 10 and add digit to it...

Answer 4

you doesn't need an array if you use another variable (initialized to zero) to store the resulting reverse number: then you do both operation in once loop ;P

Answer 5

Yep, thanks again!

Answer 6

Muhammad Hamza use strings
It might cause a bug in your program if you use division or other ways

Answer 7

And how do you join them back?

Answer 8

That’s smart
Thanks!

Answer 9

Oh and what about storing the individual digits?
I understand that an array should be used, but how do you create an array that’s just as big as the number of digits?

Answer 10

I see, thanks!
