Given two function, one is** h(x)** which is the **product** of all the number in an array A[ ] having size N and another

function **f(x)** which denotes the **GCD **of all the numbers in an array. Your task is to find the value of **h(x) ^{f(x)}**.

**Example 1:**

Input:N =2,A[] ={2, 4}Output:64Explanation:h(x) = 8, f(x) = 2, Therefore, the answer is 8^{2}= 64.

**Example 2:**

Input:N =3,A[] ={1, 3, 7}Output:21Explanation:h(x) = 21, f(x) = 1, Therefore, the answer is 21^{1}= 21.

**Your Task:**

You don't need to read input or print anything. Your task is to complete the function **getVal()** which takes an Integer N and an array of integers A[] as input and returns the answer.

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

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

**Constraints:**

1 <= N <= 10^{5}

1 <= A[i] <= 10^{5}
