/*Given an integer array and another integer element. The task is to find if the given element is present in array or not.
Ex: Input:
n = 4
arr[] = {1,2,3,4}
x = 3
Output: 2
Explanation: There is one test case with array as {1, 2, 3 4} and element to be searched as 3.  Since 3 is present at index 2, output is 2. */
