public class ExponentialSearch

Methods

Search<T>(List<T>, T)

Implements exponential search, where the search step is a multiple of 2, hence the naming. Notice that only works if the given list is sorted.

Declaration

[Algorithm(AlgorithmType.Search, "ExponentialSearch", Assumptions = "List is sorted with an ascending order.")]
[SpaceComplexity("O(1)", false, InPlace = true)]
[TimeComplexity(Case.Best, "O(1)")]
[TimeComplexity(Case.Worst, "O(log(i)), i is the index of the key in the list.")]
[TimeComplexity(Case.Average, "O(log(i)), i is the index of the key in the list.")]
public static int Search<T>(List<T> sortedList, T key)
    where T : IComparable<T>

Parameters

Type	Name	Description
System.Collections.Generic.List<T>	sortedList	A sorted list of any comparable type.
T	key	The value that is being searched for.

Returns

Type	Description
System.Int32	The index of the key in the list, and -1 if it does not exist in the list.

Type Parameters

Name	Description
T	Type of the values in the sorted list.
