Algorithms.LowerBound(TElement, TValue) Method (IList(TElement), TValue, Int32, Int32, Func(TElement, TValue, Int32))

Returns the minimum index i in the range [startIndex, endIndex - 1] such that list[i] >= value or endIndex if no such i exists

Namespace: CodeJam
Assembly: CodeJam (in CodeJam.dll) Version: 2.1.0.0

Syntax

C#

public static int LowerBound<TElement, TValue>(
	this IList<TElement> list,
	TValue value,
	int startIndex,
	int endIndex,
	Func<TElement, TValue, int> comparer
)

VB

<ExtensionAttribute>
Public Shared Function LowerBound(Of TElement, TValue) ( 
	list As IList(Of TElement),
	value As TValue,
	startIndex As Integer,
	endIndex As Integer,
	comparer As Func(Of TElement, TValue, Integer)
) As Integer

F#

[<ExtensionAttribute>]
static member LowerBound : 
        list : IList<'TElement> * 
        value : 'TValue * 
        startIndex : int * 
        endIndex : int * 
        comparer : Func<'TElement, 'TValue, int> -> int 

Parameters

 

list
Type: System.Collections.Generic.IList(TElement)
The sorted list
value
Type: TValue
The value to compare
startIndex
Type: System.Int32
The minimum index
endIndex
Type: System.Int32
The upper bound for the index (not included)
comparer
Type: System.Func(TElement, TValue, Int32)
The function with the Comparer.Compare semantics

Type Parameters

 

TElement
The list element type
TValue
The type of the value

Return Value

Type: Int32
The lower bound for the value

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IList(TElement). When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
