// TEST CASE

console.log(meleeRangedGrouping('Razor-Ranged,Invoker-Ranged,Meepo-Melee,Axe-Melee,Sniper-Ranged'));
// [ ['Razor', 'Invoker', 'Sniper'], ['Meepo', 'Axe'] ]

console.log(meleeRangedGrouping('Drow Ranger-Ranged,Chen-Ranged,Dazzle-Ranged,Io-Ranged'));
// [ ['Drow Ranger', 'Chen', 'Dazzle', 'Io'], [] ]

console.log(meleeRangedGrouping('')); // []
