Examples:
Input: [[1, 2, 3], [4, 5, 6], [10, 11, 12], [7, 8, 9]] Output: 33 Explanation: sum of all lists in the given list of lists are: list1 = 6, list2 = 15, list3 = 33, list4 = 24 so the maximum among these is of Input: [[3, 4, 5], [1, 2, 3], [0, 9, 0]] Output: 12
Method 1: list traversal in lists
We can move through the lists within the list and sum all the elements in the given list and use the max function to get the maximum sum of all the elements in the lists of the list.

33
Method 2: traversing the list
Traverse only the outer list and sum all the elements in the inner lists using the Exit: Method 3: Sum and Max Function The above function syntax max () allows us to find the sum of a list in a list using key = sum . max (list1, key = sum) , this finds the list with the maximum sum of elements, and then sum (max (list1, key = sum)) returns us the sum of that list. # Program mma Python to search
# list in the list of lists whose
# the sum of the elements is the highest
# using sum and max function and bypass
