Background: We say that a number is duplicated if the left and right halves are the same. For example, $55$ and $123123$ are both duplicated numbers, but $1221$ and $12312$ are not.

With this in mind, write the function isDuplicatedNumber$($n$)$ which takes a non$-$negative int n and returns True if n is a duplicated number and False otherwise.

Notes:

The numbers can be arbitrarily large. For example, $123456789123456789$ is a duplicated number.

While you might argue either way, we will say the $0$ is not a duplicated number.
