B - Weak Password

Score : $200$ points

Problem Statement

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:

$X_1X_2X_3X_4$

Output

If the given PIN is weak, print Weak; otherwise, print Strong.

7777

Weak

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

0112

Strong

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

9012

Weak

Note that $0$ follows $9$.
