Not really. All tests can be passed with this no-solution:

function isHamiltonianPath(gridSize, redPosition){
  const input = [...gridSize, ...redPosition].join(' ');
  console.info(input)
  return [
    '3 3 3 3',
    '3 3 2 2',
    '10 1 10 1',
    '2 2 2 1',
    '1 1 1 1'
  ].includes(input);
}
