Suzanne Collins Steals story line of the book "Battle Royale"

We all know what The Hunger Games is, but where did Suzanne Collins get the idea of kids killing kids?
Well most people believe she stole the idea by the book Battle Royale by koushun takami.

Battle Royale is about Kids killing Kids! Practically Japan isn't a  good country anymore so the teacher gets the kids to kill each other.. the trailer explains it better!

Also besides the killing kids part there is tons of similarities inbetween the two books

like the Hunger Games has districts right well in Battle Royale the kids have a number

example: boy 15 girl 15
                 boy 1 girl 1

So do you think that Suzanne Collins stole the idea? Yes or No
