Difficulty—

You are given a $4$\-digit PIN: $X_1X_2X_3X_4$, which may begin with a $0$. The PIN is said to be weak when it satisfies one of the following conditions: * All of the four digits are the same. * For each integer $i$ such that $1\leq i\leq 3$, $X_{i+1}$ follows $X_i$. Here, $j+1$ follows $j$ for each $0\leq j\leq 8$, and $0$ follows $9$. If the given PIN is weak, print `Weak`; otherwise, print `Strong`. ## Constraints * $0 \leq X_1, X_2, X_3, X_4 \leq 9$ * $X_1$, $X_2$, $X_3$, and $X_4$ are integers. ## Input Input is given from Standard Input in the following format: $X_1X_2X_3X_4$ [samples]

Samples

Input #1

Output #1

Weak

All four digits are $7$, satisfying the first condition, so this PIN is weak.

Input #2

Output #2

Strong

The first and second digits differ, and the third digit does not follow the second digit, so neither condition is satisfied.

Input #3

Output #3

Weak

Note that $0$ follows $9$.
