Bei einem Array arr aus ganzzahligen Elementen besteht die Aufgabe darin, den Bereich und den Koeffizienten des Bereichs des gegebenen Arrays zu finden, wobei gilt: 
Bereich: Differenz zwischen dem Maximalwert und dem Minimalwert in der Verteilung. 
Bereichskoeffizient: (Max – Min) / (Max + Min).
Beispiele: 
 

Eingabe: arr[] = {15, 16, 10, 9, 6, 7, 17} 
Ausgabe: Bereich: 11 
Koeffizient des Bereichs: 0,478261 
Max = 17, Min = 6 
Bereich = Max – Min = 17 – 6 = 11 
Koeffizient des Bereichs = (Max – Min) / (Max + Min) = 11 / 23 = 0,478261
Eingabe: arr[] = {5, 10, 15} 
Ausgabe: Bereich: 10 
Koeffizient des Bereichs: 0,5 
 

Ansatz: Finden Sie das maximale und minimale Element aus dem gegebenen Array und berechnen Sie die Reichweite und den Koeffizienten der Reichweite wie folgt: 
 

• Bereich = Max – Min
• Reichweitenkoeffizient = (Max – Min) / (Max + Min)

Unten ist die Implementierung des obigen Ansatzes:
