That's the right algorithm, and the best you'll do in CFML. However,
you've got a couple bits that are slightly off. Here's the right
bits:
<cfset found = false />
<cfloop list="#listOne#" index="i">
<cfif listFind(listTwo, i)>
<cfset found = true />
<cfbreak />
</cfif>
</cfloop>
You want listFind instead of listContains, so you don't do substring
matching (e.g. "23" shouldn't match "1234"). And you can do a CFBREAK
once you find a match because searching the rest of the values is
irrelevant.
