Syntax

public class BinarySearch

Methods

Search<T>(List<T>, T, Int32, Int32)

Searches in a sorted list of any comparable type, and returns the index of the key using binary search, and -1 if it is not found.

Declaration

[Algorithm(AlgorithmType.Search, "BinarySearch", Assumptions = "List is sorted with an ascending order.")]
[SpaceComplexity("O(1)", false, InPlace = true)]
[TimeComplexity(Case.Best, "O(1)")]
[TimeComplexity(Case.Worst, "O(Log(n))")]
[TimeComplexity(Case.Average, "O(Log(n))")]
public static int Search<T>(List<T> sortedList, T key, int startIndex, int endIndex)
    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.
System.Int32	startIndex	The lowest (left-most) index of the list - inclusive.
System.Int32	endIndex	The highest (right-most) index of the list - inclusive.

Returns

Type	Description
System.Int32	The index of the key in the list, and -1 if it is absent from the array.
