Given an array **A[]** that stores all number from **1** to **N** (both inclusive and sorted) and **K** queries.

The task is to do the following operations on array elements :

1. **UNION** X Z : Perform union of **X** and **Z** i.e. parent of **Z** will become the parent of **X**.

2. **FIND** X: Find the parent of **X** and print it.

Note: Initially all are the parent of themselves.

**Input:**
N = 5, K = 4
queries[] = {{find 4},
{find 1},
{unionSet 3 1},
{find 3}}
**Output:**
4 1 1
**Explanation:**
1. The parent of 4 is 4. Hence the output is 4.
2. The parent of 1 is 1. Hence the output is 1.
3. After performing unionSet 3 1, parent of 3 becomes 1,
since, parent of 1 is currently 1 itself.
4. The parent of 3 is now 1. Hence, the output is 1.

**Your Task:**

You don't need to read input or print anything. Your task is to complete the functions- **find****()** which takes an array **A**[]** **and an integer **X **as an input parameter and return the parent of **X **and the function **unionSet() **which takes an array **A**[]** **and two integers **X **and **Z **and performs the **union** of **X** and **Z**.

**Expected Time Complexity:** O(N)

**Expected Auxiliary Space:** O(1)

**Constraints:**

1 <= N, K <= 100
