Controleer of de gegeven string kan worden opgesplitst in vier verschillende strings
Probeer het eens op GfG Practice 
Uitvoer
Gegeven een string is het de taak om te controleren of we deze in 4 strings kunnen splitsen, zodat elke string niet leeg is en verschilt van de andere.
Voorbeelden:
Invoer : str[] = 'geeksforgeeks'
Uitvoer : Ja
'geeks' 'for' 'gee' 'ks' zijn vier verschillende strings die uit een gegeven string kunnen ontstaan.
Invoer : str[] = 'aaabb'
Uitvoer : Nee
Kijk of de lengte van de snaar groter is dan of gelijk is aan 10, dan kan deze elke keer in vier delen worden opgesplitst. Stel dat de lengte 10 is, dan kan een string met lengte 1 2 3 4 worden gemaakt.
Voor een snaar met een lengte van minder dan 10 kunnen we brute kracht gebruiken, d.w.z. alle mogelijke manieren doorlopen om de snaar te splitsen en ze allemaal controleren.
Als lengte is meer dan 10
terugkeer waar
Anders (Als de lengte minder dan 10 is)
Gebruik de Brute Force-methode om te controleren of we het in vier verschillende reeksen kunnen opsplitsen.
Hieronder vindt u de implementatie van het bovenstaande idee.
