Python – Suffix List Sum
Nowdays, especially in the field of competitive programming, the utility of computing suffix sum is quite popular and features in many problems. Hence, having a one liner solution to it would possess a great help. Let’s discuss certain way in which this problem can be solved.
Method : Using list comprehension +
sum() + list slicing
This problem can be solved using the combination of above two functions in which we use list comprehension to extend logic to each element, sum function to get the sum along, slicing is used to get sum till the particular index.
The original list : [3, 4, 1, 7, 9, 1] The suffix sum list is : [1, 10, 17, 18, 22, 25]
