Given an integer num, return the smallest and largest integers in a sequence of consecutive integers that sum to num. There may be multiple sequences that work; return the longest sequence. Return null if there are no solutions of at least 2 consecutive integers.

Example:

maxConsecutiveSum(45) returns [1,9].

Notice that [14,16] is also a valid range that adds to 45, but there is another solution with a larger number of consecutive integers.
