You are given an integer n.

Form an integer x by concatenating all digits of n that are not equal to $0$, preserving their original relative order. If n has no digits other than $0$, then x is equal to $0$.

Let sum be the sum of all digits in x.

Return the product of x and sum.

Constraints:

• $0 \leq$ n $\leq 10^9$
