Checking if a list of strings can be chained

Question

Question

Implement a function bool chainable(vector v), which takes a set of strings as parameters and returns true if they

Answer 1

seperatedly check for "Is chainable" and is "cylcic"

if it's to be cyclic it must be chainable first. you could do something like this:

if (IsChainable)
{
  if (IsCyclic() { ... }
}

Note: That's the case if you check only the first and last element of the chain for "cylic".
