Given an sorted array A of size N. Find number of elements which are less than or equal to given element X.
Example 1:
Input:
N = 6
A[] = {1, 2, 4, 5, 8, 10}
X = 9
Output:
5
Example 2:
Input:
N = 7
A[] = {1, 2, 2, 2, 5, 7, 9}
X = 2
Output:
4
Your Task:
You don't need to read input or print anything. Your task is to complete the function countOfElements() which takes the array A[], its size N and an integer X as inputs and returns the number of elements which are less than or equal to given element.
Expected Time Complexity: O(N) Expected Auxiliary Space: O(1)
Constraints:
1 <= N <= 105
1 <= Ai <= 105
0 <= X <= 105

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
