Next semester's course

Problem

Next semester's course starts as a copy of this one: the same code, the same teacher and the same weekly hours. The hours belong to each course, but the teacher is one real person, so a phone number update must reach both courses. Write the Course copy constructor, deciding each field, then run the changes.

Input, output and limits

Input: Line 1: course code, teacher name and phone. Line 2: w, then w weekly hours. Line 3: q. Next q lines: CODE newCode or HOURS week h (both for next semester), or PHONE number (the teacher's new phone).
Output: This semester: <code> by <teacher> (<phone>) hours <hours> and the same line for Next semester:.
Constraints: 1 ≤ w ≤ 16
0 ≤ q ≤ 20
0 ≤ h ≤ 10
Codes and names are single words

Example

Input

CS201 Rao 9845011111
3
3 3 4
3
CODE CS201N
HOURS 3 2
PHONE 9845022222

Output

This semester: CS201 by Rao (9845022222) hours 3 3 4
Next semester: CS201N by Rao (9845022222) hours 3 3 2

The hours change only next semester; the new phone shows in both.

Hints

Try the problem first. Open one hint at a time.

Hint 1

Ask for each field: does next semester own it, or point to the same real thing?

Hint 2

Clone the hours array; keep the teacher reference with plain =; String code needs no copy.

Hint 3

Apply PHONE to this semester's teacher: if the teacher is shared, next semester sees it too.

Write your Java code, run it on the examples and submit it to hidden tests.
