	/**
	Given a sequence of integers as an array, determine whether it is possible to obtain a strictly increasing sequence by removing no more than one element from the array.

	Example

	For sequence = [1, 3, 2, 1], the output should be
	almostIncreasingSequence(sequence) = false;

	There is no one element in this array that can be removed in order to get a strictly increasing sequence.
