We can do this very efficiently by making a structure that we can index in sub-linear time.

Ruby max integer
... big they can be.
If you are looking for the machine's size, i.e. 64- or 32-bit, I found this trick at ruby-forum.com:
machine_bytes = ['foo'].pack('p').size
machine_bits = machine_bytes * 8
machine_max_signed = 2**(machine_bits-1) - 1
machine_max_unsigned = 2**machine_bits - 1
If you are look...
Add Variables to Tuple
...n. However, you can concatenate or slice them to form new tuples:
a = (1, 2, 3)
b = a + (4, 5, 6) # (1, 2, 3, 4, 5, 6)
c = b[1:] # (2, 3, 4, 5, 6)
And, of course, build them from existing values:
name = "Joe"
age = 40
location = "New York"
joe = (name, age, location)

How to determine the longest increasing subsequence using dynamic programming?

OK, I will describe first the simplest solution which is O(N^2), where N is the size of the collection. There also exists a O(N log N) solution, which I will describe also. Look here for it at the section Efficient algorithms.
I will assume the indices of the array are from 0 to N - 1...
