Finding Array Difference!

[micjohnson]

Is there any logic available to find the difference between two arrays.

OldArray = "F5,PLB,REC,TOL,ZMM,ZRW"
NewArray = "F5,REC,TOL,ZMM,ZRW,ZZZ"

I need to get whats removed and whats added.

(eg. Here PLB removed and ZZZ added)

Thanks in advance.

this is one way to do it


<cfset myNewArray = ArrayNew(1)>
<cfset myNewArray[1] = "F5">
<cfset myNewArray[2] = "PLB">
<cfset myNewArray[3] = "REC">
<cfset myNewArray[4] = "TOL">
<cfset myNewArray[5] = "ZMM">
<cfset myNewArray[6] = "ZRW">

<cfset myOldArray = ArrayNew(1)>
<cfset myOldArray[1] = "F5">
<cfset myOldArray[2] = "REC">
<cfset myOldArray[3] = "TOL">
<cfset myOldArray[4] = "ZMM">
<cfset myOldArray[5] = "ZZZ">


<cfset myNewArrayList = ArrayToList(myNewArray, ',')>
<cfset myOldArrayList = ArrayToList(myOldArray, ",")>

<cfoutput>
<cfloop list="#myNewArrayList#" index="i">
<cfif ListContainsNoCase(myOldArrayList, i) EQ 0>
this element is added --> #i# <br>
</cfif>
</cfloop>

<cfloop list="#myOldArrayList#" index="k">
<cfif ListContainsNoCase(myNewArrayList, k) EQ 0>
this element is removed --> #k# <br>
</cfif>
</cfloop>
</cfoutput>
