Time Complexity
$O(n)$
Space Complexity
$O({1})$ words
(Derived: Checking an inequality that involves 3 summations, of max value $O(n^2)$ each (assuming max degree $\leq n$) which is $O(1)$ words in our Word RAM. We check this inequality for each $k = 1, \ldots, n$, but you can store the summations dynamically, so you only need to run $O(1)$ operations per iteration)
Description
Makes use of (0,1) matrix properties, checks a property of the input values through the lens of an adjacency matrix
