How assign rev command to a variable in shell

Question

I wanted to direct the output of rev command to a variable, I tried different methods and didn't work.

 read -p "Enter the number: " n   
 echo $n | rev
 echo "new n is: $p"

I want to assign the output of line 2 to p. How?

Thank you,

To store the output of a command in a variable, use the `varname=$(command)` syntax, in this example `p=$(echo $n | rev)` — janos, Jul 31 '16 at 16:03

To store the output of a command in a variable use a $(...) command substitution:

p=$(echo $n | rev)
