Please any one of  you answer the below question .

 

1.       Analyse FunctionX (Below) and describe what the function does.

    'InputParam is a collection of integers

    Public Function FunctionX(ByVal InputParam As Collection) As Integer

        Dim returnVal As Integer

 

        If (InputParam.Count > 0) Then

 

            'The enumerator object allows you to traverse the collection

            Dim collectionEnum As IEnumerator

            collectionEnum = InputParam.GetEnumerator()

 

            Dim int1 As Integer = 0

            Dim int2 As Integer = 0

            While (collectionEnum.MoveNext())

 

                int2 = CType(collectionEnum.Current, Integer)

 

                If int2 > int1 Then

                    int1 = int2

                End If

 

            End While

 

            returnVal = int1 + 1

        Else

            returnVal = 0

        End If

        Return returnVal

    End Function

 

it simply return the last enumerator largest integer value plus one to the calling method if input collection doesn`t contain any value then it return 0 to calling method

Hi,

Then purpose of FunctionX is fetch the largest value from collection and return the largestvalue increment with 1.

How It work ....
FunctionX recieve a collection InputParam.
If (InputParam.Count > 0) Then==>First Check the length of this collection

Dim collectionEnum As IEnumerator ==>Create collectionEnum object IEnumerator type
collectionEnum = InputParam.GetEnumerator()==>Get all elements From Collection and set in collectionEnum
Dim int1 As Integer = 0

Dim int2 As Integer = 0

While (collectionEnum.MoveNext()) ==> Loop for fetching all element and traverse loop at to end of collection


int2 = CType(collectionEnum.Current, Integer)==> fetch currect element and set value in int2
If int2 > int1 Then ==> If currect value is > Previous value , First time int1 is 0

int1 = int2 ==>Set large value in int1

End If

End While
returnVal = int1 + 1 ==> return value will be LargeValue +1

Else

returnVal = 0 ==> If collection has no element then return 0

End If

Return returnVal ==> return final value

End Function



Thanks & Regards ,

This function checks if there is element in the collection it adds 1 to the largest element in the collection and returns the same otherwise returns 0.
