Python statistics.sum() function can also be used to find the average of data values in Python list.Time Complexity: O(N), Here N is the number of elements in the list. Auxiliary Space: O(1), As constant extra space is used. Example 8: Using Bitwise OR operator. The idea is to check whether the last bit of the number is set or not. If the last bit is set then the number is odd, otherwise even.max_num = i. print(max_num) Also if you want to find the index of the resulting max, print(a.index(max_num)) Direct approach by using function max () max () function returns the item with the highest value, or the item with the highest value in an iterable. Example: when you have to find max on integers/numbers. a = (1, 5, 3, 9) print(max(a))

Time complexity: O(nlogk), where n is the length of the list and k is the number of largest elements to be returned. In this case, k is 1, so the time complexity is O(nlog1) = O(n). Auxiliary Space: O(k), where k is the number of largest elements to be returned. In this case, k is 1, so the auxiliary space is O(1).
