Given a matrix with **n** rows and **m **columns. Your task is to find the kth element which is obtained while traversing the matrix spirally. You need to complete the method** findK** which takes four arguments the first argument is the matrix A and the next two arguments will be n and m denoting the size of the matrix A and then the forth argument is an integer k denoting the kth element . The function will return the kth element obtained while traversing the matrix spirally.

**Example 1****:**

**Input:
**n = 3, m = 3, k = 4
A[][] = [[1 2 3],
[4 5 6],
[7 8 9]]
**Output: **6**
Explanation: **The matrix above will look
like
1 2 3
4 5 6
7 8 9
and the 4th element in spiral fashion
will be 6 .

**Your Task:**

You only need to implement the given function **findK()**. Do not read input, instead use the arguments given in the function. Return the K'th element obtained by traversing matrix spirally.

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

**Expected Auxiliary Space:** O(N*M)

**Constraints:**

1<=n,m<=20

1<=k<=n*m
