You are given an integer $N$ between $-10^{18}$ and $10^{18}$ (inclusive). Find an integer $x$ between $0$ and $998244353 - 1$ (inclusive) that satisfies the following condition. It can be proved that such an integer is unique. * $N-x$ is a multiple of $998244353$. ## Constraints * $N$ is an integer between $-10^{18}$ and $10^{18}$ (inclusive). ## Input Input is given from Standard Input in the following format: $N$ [samples]

Samples

Input #1

998244354

Output #1

1

$998244354-1 = 998244353$ is a multiple of $998244353$, so the condition is satisfied.

Input #2

\-9982443534

Output #2

998244349

$-9982443534-998244349= -10980687883$ is a multiple of $998244353$, so the condition is satisfied.
