Sum of Digits and Augmented Number

Given a non-negative integer \(n\), let \(S(n)\) denote the sum of its digits. Your task is to compute the value of \(f(n)\) defined as:

\[ f(n) = n + S(n), \]

Input Constraint: \(0 \leq n \leq 10^7\).

Examples:

• If \(n = 123\), then \(S(123) = 1+2+3 = 6\) and thus \(f(123) = 123 + 6 = 129\).
• If \(n = 2021\), then \(S(2021) = 2+0+2+1 = 5\) and thus \(f(2021) = 2021 + 5 = 2026\>.

Implement a program that reads an integer \(n\) from standard input and outputs \(f(n)\) to standard output.

inputFormat

The input consists of a single line containing one non-negative integer \(n\).

outputFormat

Output the computed value \(f(n) = n + S(n)\) on a single line.
