@dheeraj : u are right . i dint read the question properly . i thot there are total n glasses so i answerd : n/4 swaps . bt since we have 2n glass so we need n/2 swaps . i guess gopi did the same mistake @sachin : yes u are also correct since the glasses are identical the order of swapping doesnt matter . yes u can do that way also . the onli thing is dat u will require n/2 swaps .
