Accumulating List

Create a function that takes in a list and returns a list of the accumulating sum.

Examples

accumulating_list([1, 2, 3, 4]) ➞ [1, 3, 6, 10]
# [1, 3, 6, 10] can be written as  [1, 1 + 2, 1 + 2 + 3, 1 + 2 + 3 + 4]

accumulating_list([1, 5, 7]) ➞ [1, 6, 13]

accumulating_list([1, 0, 1, 0, 1]) ➞ [1, 1, 2, 2, 3]

accumulating_list([]) ➞ []

Notes

An empty list input [] should return an empty list [].
