Implement a Queue using an Array. Queries in the Queue are of the following type:

**(i)** 1 x (a query of this type means pushing **'x'** into the queue)

**(ii)** 2 (a query of this type means to pop element from queue and print the poped element)

**Example 1:**

**Input:
**Q = 5
Queries = 1 2 1 3 2 1 4 2
**Output: **2 3**
Explanation:
**In the first test case for query
1 2 the queue will be {2}
1 3 the queue will be {2 3}
2 poped element will be 2 the
queue will be {3}
1 4 the queue will be {3 4}
2 poped element will be 3

**Example 2:**

**Input:
**Q = 4
Queries = 1 3 2 2 1 4
**Output: **3 -1**
Explanation:
**In the second testcase for query
1 3 the queue will be {3}
2 poped element will be 3 the
queue will be empty
2 there is no element in the
queue and hence -1
1 4 the queue will be {4}.

**Your Task :**

You are required to complete the two methods **push()** which take one argument an integer **'x'** to be pushed into the queue and **pop()** which **returns **a **integer **poped out from othe queue. If the queue is empty, it should return -1 on a pop operation.

**Expected Time Complexity: **O(1) for both **push() **and **pop()**.

**Expected Auxiliary Space: **O(1) for both **push() **and **pop()**.

**Constraints:**

1 ≤ Q ≤ 10^{5}

1 ≤ x** **≤ 10^{5}
