There is a rectangle in the xy-plane. Each edge of this rectangle is parallel to the 2or y-axis, and its area is not zero.
Given the coordinates of three of the four vertices of this rectangle, (P,Q), (A,B), and (X,Y), find the coordinates of the other vertex.
Constraints
All numbers are between -100 and +100.
There uniquely exists a rectangle with all of (P,Q), (A,B), and (X,Y) as vertices, edges parallel to the xor y-axis, and a non-zero area.
All values in input are integers.
Input
Input is given from Standard Input in the following format:
P Q
A B
X YOutput

Sample Output 1
The other vertex of the rectangle with vertices (−1,−1),(−1,2),(3,2) is (3,−1).
Problem Statement
One day, Tina got up at exactly B minutes past A o’clock (in 24-hour clock), and Rahul got up at exactly D minutes and 1 second past C o’clock.
If Tina got up earlier than Rahul, print Tina; otherwise, print Rahul.
Constraints
- 0 < A < 23
- 0 ≤ B ≤ 59
- 0< C < 23
- 0 ≤ D ≤ 59
- All values in input are integers.

Codeforces separates its users into 4 divisions by their rating:
- For Division 1: 1900 ≤ rating
- For Division 2: 1600 ≤ rating ≤ 1899
- For Division 3: 1400 ≤ rating ≤ 1599
- For Division 4: rating ≤ 1399
Given a rating, print in which division the rating belongs.
Input
The first line of the input contains an integer 𝑡 (1≤𝑡≤10^4) — the number of testcases.
The description of each test consists of one line containing one integer rating (−5000≤rating≤5000).
Output
For each test case, output a single line containing the correct division in the format “Division X”, where 𝑋 is an integer between 1 and 4 representing the division for the corresponding rating.
Sample I/O
Sample Input 1
Sample Output 1
Note
For test cases 1−4, the corresponding ratings are −789, 1299, 1300, 1399, so all of them are in division 4.
For the fifth test case, the corresponding rating is 1400, so it is in division 3.
For the sixth test case, the corresponding rating is 1679, so it is in division 2.
For the seventh test case, the corresponding rating is 2300, so it is in division 1.
This is an optional and open-ended problem. Feel free to get creative.
