hey
what's wrong with this code for alien rhyme (got WA):
###########The Code############
const readline = require('readline');
var rl = readline.createInterface(process.stdin, process.stdout);
var TCNum=0;
var TCmax=null;
var waitFor='T';
var n;
var wl=[];
var thisWord;
var thatWord;
var mathed=0;
var isPair=-1;
var wordCount=0;
rl.on('line', function(data) {
if(waitFor=='T'){
TCmax=parseInt(data);
waitFor='N';
}else if(waitFor=='N'){
n=parseInt(data);
wl=[];
waitFor='W';
}else if(waitFor=='W'){
wl.push(data);
if(wl.length==n)
{
wordCount=0;
while(wl.length)
{
thisWord=wl[0];
isPair=-1;
for(var i=0;i<thisWord.length;i++)
{
mathed=0;
for(var ii=1;ii<wl.length;ii++)
{
thatWord=wl[ii];
if(thisWord.substr(thisWord.length-1-i)==thatWord.substr(thatWord.length-1-i))
{
mathed++;
isPair=ii;
}
}
if(mathed<=1)
{
break;
}
}
if(mathed==1)
{
wordCount++;
wl.splice(isPair,1);
wl.splice(0,1);
}else{
wl.splice(0,1);
}
}
console.log("Case #"+(TCNum+1)+": "+(wordCount*2));
waitFor='N';
checkCount();
}
}
function checkCount()
{
TCNum++;
if(TCNum==TCmax)
{
rl.close();
}
}
}).on('close',function(){
process.exit(0);
});
