Error

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).

**Constraints:**

1 ≤ N ≤ 10^{7}
