**Mr. Gora** is extremely disappointed with the performance of the students in his subject.

He felt that something was AMISS. Therefore, he decided to conduct another **NIGHT SHOW** **(lab exam :P )** for his students to test their basic understanding of the subject.

The question was extremely **"simple"**.

The students are initially **provided an array with no elements at all.**
(the indexing of the array is **1-based**).

The students are provided with some **queries** as follows -

**Type 1**: Consider**the first index in the array which is unallocated i.e empty**.**Place**the**integer K at that index**.**Type 2**: Consider**all the indices between L and R**(**inclusive of L and R**as well). Find the number of**all the integers less than K**in this range.**Type 3**: Consider**all the indices between L and R**(**inclusive of L and R**as well). Find the number of**all the integers equal to K**in this range.**Type 4**: Consider**all the indices between L and R**(**inclusive of L and R**as well). Find the number of**all the integers greater than K**in this range.

Students have to solve this question anyhow to pass the exam.

You being an excellent coder have to help these students.

**Input**

The first line of the input contains an integer **Q** denoting the number of the queries.
**Q** lines follow.
The queries are of the following form.

- Query 1 is like
**"1 K"**. - Query 2 is like
**"2 L R K"**. - Query 3 is like
**"3 L R K"**. - Query 4 is like
**"4 L R K"**.

**Output**

For each query of type 2, 3 and 4, you need to output answer on a separate line.

**Constraints**

**1<=Q<=6*10 ^{5}**

Explanation

10 queries are provided.

**Query 1**
The first unallocated **index is 1.**
So **4** is placed there.

**Query 2**
The first unallocated **index is 2.**
So **5** is placed there.

**Query 3**
The first unallocated **index is 3.**
So **7** is placed there.

**Query 4**
The first unallocated **index is 4.**
So **4** is placed there.

**Query 5**
In the **range 1 to 3,** we have **no integer less than 4. So, the output is 0.**

**Query 6**
In the **range 2 to 4,** we have **1 integer equal to 5. So, the output is 1.**

**Query 7**
The first unallocated **index is 5.**
So **6** is placed there.

**Query 8**
In the **range 1 to 5,** we have **3 integers greater than 4. So, the output is 3.**

**Query 9**
In the **range 4 to 5,** we have **1 integer less than 5. So, the output is 1.**

**Query 10**
In the **range 2 to 4,** we have **2 integer less than 7. So, the output is 2.**
