Given a sequence of numbers and a start and an end delimiters, how to find the index (start and end) of all possible sequence of numbers between delimiters (sequences can be of any length). Example:
v = [1 1 0 2 0 2 1 2 1 1 1 0 2 1 2 0 0 1 1 1 1 1 1 2 1 0 ]
A list of non-overalpping sequences and their start and end index that begin with 2 and end with 0 would be:
[2 0]
[2 1 2 1 1 1 0]
[2 1 2 0]
[2 1 0]
I feel like this could be solved using regular expression.

If the numbers are always positive integers <10 then this is easy. If the values can be >=10 or if you want to consider non-integer values then the task requires a bit more thought. What restrictions/limits do you have on the number values?

you could convert the array to a string or char array and then use extractBetween() which does what you want
