Biggest Sublist

For a given list, determine the biggest possible sum between consecutive terms, as well as the initial and final position of the terms.

Examples

big_sub([4, -3, 5, -7, 5]) ➞ [6 (sum), 0 (start), 2 (end)]

big_sub([4, -3, -5, 7, 5]) ➞ [12, 3, 4]

big_sub([2, -3, 2, -3, 2]) ➞ [2, 4, 4]

Notes

• If the biggest sum is repeated at several intervals, return the starting and ending positions of the latest interval.
• The list will always have positive numbers.
