This is a question from the ACM contest question archive......
(you can also register for the demo online judge to test yourself,

If I store n ignore words to an array,
then I should check n*(length of each title)*(no. of titles)....
Obviously it is not good...
(and in fact it can't be accepted by the demo judge...)
Any idea??
