The goal is to test if a consecutive sequence can be formed. A consecutive sequence is defined as a sequence of incrementing numbers (e.g. 1, 2, 3 or 5, 6, 7, 8). The twist is that you have to consider the combination of vectors as shown. You can combine any two elements from different vectors.
{-5 1 3 5} => {3 5 1 -5} => {3+4 5+3 1+8 15-5} = {7 8 9 10} => true
{4 3 8 15} => {4 3 8 15}Also important is that the vectors can be of different sizes, allowing for partially unpaired numbers in some cases.
{2 2 2 } => {2 2 2 0} => {2+5 2+6 2+7 10+0} = {7 8 9 10} => true
{10 5 6 7} => {5 7 6 10}
