Every Thursday is the craziest day for students at a certain university starting with the letter T—this is partly because the English abbreviation for "Thursday" (THU) is the same as the university's abbreviation. Therefore, people also call every Thursday "Crazy THU Day."
Please write a program that determines whether a given date is a "Crazy THU Day."
Input
The input is read from standard input.
The input consists of a single line containing three positive integers $y, m, d$, representing the date $y$ year $m$ month $d$ day.
Output
The output is written to standard output.
Output a single line. If the date is a Thursday, output Crazy THU!. Otherwise, output Not crazy enough..
Examples
Input 1
2024 2 29
Output 1
Crazy THU!
Input 2
2024 3 30
Output 2
Not crazy enough.
Constraints
For $10\%$ of the data, it is guaranteed that $y=2024, m=2, d=29$.
For $30\%$ of the data, it is guaranteed that $y=2024, m=2$.
For $50\%$ of the data, it is guaranteed that $y=2024$.
For $70\%$ of the data, it is guaranteed that $y \le 2099$.
For all test data, it is guaranteed that $2001 \le y \le 9999$, and the given date is a valid date.
Note
Zeller's congruence for calculating the day of the week is: $w=y+[y/4]+[c/4]-2c+[13(m+1)/5]+d-1$, where $c$ is the first two digits of the year, $y$ is the last two digits of the year, $m$ is the month (where January and February are treated as months 13 and 14 of the previous year), $d$ is the day, and $[x]$ denotes the floor function.
Taking the calculated $w$ modulo $7$ (if $w$ is negative, add a multiple of $7$ to make it non-negative before taking the modulo) results in an integer between $0$ and $6$, where $0$ represents Sunday, $1$ represents Monday, and so on.
