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.

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.

Constraints

• $0 \leq X_1, X_2, X_3, X_4 \leq 9$
• X_1, X_2, X_3, and X_4 are integers.

Sample Input 1

7777

Sample Output 1

Weak

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

Sample Input 2

0112

Sample Output 2

Strong

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

Sample Input 3

9012

Sample Output 3

Weak

Note that 0 follows 9.
