Açıklamalar
Bu yönteme yapılan çağrıdan sonra, myArray[i]
öğesinde i
dizideki herhangi bir dizindir, myArray[j]
konumuna taşınır; burada j
(myArray.Length + myArray.GetLowerBound(0)) - (i - myArray.GetLowerBound(0)) - 1
eşittir.
Bu yöntem, n
array
Length olduğu bir O(n
) işlemidir.
F# dilinde bunun yerine Array.rev işlevi kullanılabilir.
Aşağıdaki örnekte gösterildiği gibi, Reverse yöntemi pürüzlü bir diziyi ters çevirmek için kullanılabilir. Geçerli kültürün takviminde geçerli yılın her ayı için bir öğe içeren bir pürüzlü dizi başlatır. Her öğe, o ayın gün sayısı kadar öğe içeren bir dizi içerir. Örnek dizinin içeriğini görüntüler, Reverse yöntemini çağırır ve ardından ters çevrilmiş dizinin içeriğini görüntüler.

Açıklamalar
Bu yönteme yapılan çağrıdan sonra, myArray[i]
öğesinde i
dizideki herhangi bir dizindir, myArray[j]
konumuna taşınır; burada j
(myArray.Length + myArray.GetLowerBound(0)) - (i - myArray.GetLowerBound(0)) - 1
eşittir.
Reverse yöntemi, pürüzlü bir diziyi ters çevirmek için kullanılabilir.
Bu yöntem, n
length
olduğu bir O(n
) işlemidir.
