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.
Note: sequence a0, a1, ..., an is considered to be a strictly increasing if a0 < a1 < ... < an. Sequence containing only one element is also considered to be strictly increasing.
- For sequence = [1, 3, 2, 1], the output should be solution(sequence) = false.
There is no one element in this array that can be removed in order to get a strictly increasing sequence.
- For sequence = [1, 3, 2], the output should be solution(sequence) = true.
You can remove 3 from the array to get the strictly increasing sequence [1, 2]. Alternately, you can remove 2 to get the strictly increasing sequence [1, 3].
