Elements in the Range
Basic Accuracy: 17.42% Submissions: 264 Points: 1

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.

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 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 ≤ 107
