Virtual contest is a way to take part in past contest, as close as possible to participation on time. It is supported only ICPC mode for virtual contests.
If you've seen these problems, a virtual contest is not for you - solve these problems in the archive.
If you just want to solve some problem from a contest, a virtual contest is not for you - solve this problem in the archive.
Never use someone else's code, read the tutorials or communicate with other person during a virtual contest.

F. MEX Queries

standard inputoutput

standard outputYou are given a set of integer numbers, initially it is empty. You should perform *n* queries.

There are three different types of queries:

- 1
*l**r*— Add all missing numbers from the interval [*l*,*r*] - 2
*l**r*— Remove all present numbers from the interval [*l*,*r*] - 3
*l**r*— Invert the interval [*l*,*r*] — add all missing and remove all present numbers from the interval [*l*,*r*]

After each query you should output MEX of the set — the smallest positive (MEX ≥ 1) integer number which is not presented in the set.

Input

The first line contains one integer number *n* (1 ≤ *n* ≤ 10^{5}).

Next *n* lines contain three integer numbers *t*, *l*, *r* (1 ≤ *t* ≤ 3, 1 ≤ *l* ≤ *r* ≤ 10^{18}) — type of the query, left and right bounds.

Output

Print MEX of the set after each query.

Note

Here are contents of the set after each query in the first example:

- {3, 4} — the interval [3, 4] is added
- {1, 2, 5, 6} — numbers {3, 4} from the interval [1, 6] got deleted and all the others are added
- {5, 6} — numbers {1, 2} got deleted
