The condition always yields false. Please run and test the program before creating pull request.

trim the whitespaces from num before taking half_len. Rust donot remove whitespaces by default.

use num.trim() to remove whitespaces.

{println!("it is palindrome");}
else
{ println!("it is not palindrome");}
