Given a floating point number in string format s, check whether it is even or odd.

Example 1:
Input:
n = 4
s = 97.8
Output: EVEN
Explanation: 8 is even number.
Example 2:
Input:
n = 6
s = 100.70
Output: ODD
Explanation: Trailing 0s after dot do not matter.
Your Task:
You don't need to read input or print anything. Your task is to complete the function isEven() which accepts a string s(floating point number) and the integer n(denotes the length of the string s) as input parameter and returns a boolean value.

Expected Time Complexity: O(n)
Expected Auxiliary Space: O(1)

Constraints:
1 <= n <= 10^{5}
n is the length of the string s.^{ }
