M_CodeJam_Algorithms_PartitionPoint__1_1

Algorithms.PartitionPoint(T) Method (IList(T), Int32, Predicate(T))

Returns the index i in the range [startIndex, list.Count - 1] such that predicate(list[j]) = true for j < i and predicate(list[k]) = false for k >= i or list.Count if no such i exists

Remarks

The list should be partitioned according to the predicate

Syntax

C#

public static int PartitionPoint<T>(
	this IList<T> list,
	int startIndex,
	Predicate<T> predicate
)

VB

<ExtensionAttribute>
Public Shared Function PartitionPoint(Of T) ( 
	list As IList(Of T),
	startIndex As Integer,
	predicate As Predicate(Of T)
) As Integer

F#

[<ExtensionAttribute>]
static member PartitionPoint : 
        list : IList<'T> * 
        startIndex : int * 
        predicate : Predicate<'T> -> int 

Parameters

 

list

Type: System.Collections.Generic.IList(T)
The sorted list

startIndex

Type: System.Int32
The minimum index

predicate

Type: System.Predicate(T)
The predicate

Type Parameters

 

T

The list element type

Return Value

Type: Int32
The partition point

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IList(T). 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).
