Given an array arr[] containing positive elements. ‘A’ and ‘B’ are two numbers defining a range. The task is to check if the array contains all elements in the given range.

Example 1:

Input: N = 7, A = 2, B = 5
arr[] = {1, 4, 5, 2, 7, 8, 3}
Output: Yes
Explanation: It has elements between
range 2-5 i.e 2,3,4,5

Example 2:

Input: N = 7, A = 2, B = 6
arr[] = {1, 4, 5, 2, 7, 8, 3}
Output: No
Explanation: Array does not contain 6.

Your Task:
This is a function problem. You don't need to take any input, as it is already accomplished by the driver code. You just need to complete the function check_elements() that takes array arr, integer N, integer A, and integer B as parameters and returns the boolean True if array elements contain all elements in the given range else boolean False.

Note: If the array contains all elements in the given range then driver code outputs Yes otherwise, it outputs No

Expected Time Complexity: O(N). Expected Auxiliary Space: O(1).
