Hello there..
I'd like to share with you one of the problems which I read once in A problem solving book.. I wonder if anyone knew it, and subsequently could answer it..
Now, see the circles on the right side. It is required to cross these circles with max. 4 straight lines, but the lines must be connected. It means you can't raise your hand off the paper when you want to make the next line..
PS: this problem has more than one solution. Now, let's see about yours..
Please note that comments will
