Given two integers, n and m. The task is to check the relation between n and m.
Example 1:
Input:
n = 4
m = 8
Output:
lesser
Explanation:
4 < 8 so print 'lesser'.
Example 2:
Input:
n = 8
m = 8
Output:
equal
Explanation:
8 = 8 so print 'equal'.
Your Task:
You don't need to read input or print anything. Your task is to complete the function compareNM() which takes two integer n and m as input parameters and returns string
'lesser' if n < m
'equal' if n == m
'greater' if n > m
Expected Time Complexity: O(1)
Expected Auxiliary Space: O(1)
Constraints:
-10000 <= m <= 10000
-10000 <= n <= 10000
