Character device driver status by Vijay Partap

I have done following things:

1. Open operation

2. Trim function

For the time being, character device driver is working properly with trim function. But its proper functionality can be seen after writing in the device.

Answer for jackpot question for paper puzzle

first fold the sheet in half, get a pair of scissors and cut about an inch in from the side starting from the folded edge cutting towards the open edge, but stop about 1 1/2 inces from the open edge. then make a similar cut next to the first one but go from the open edge to the folded edge (remember not to cut all the way through), then you just reapeat alternating as you go until you run out of space (make sure you end with a cut from the folded edge to open edge (trim the end off if it if theres too much extra). now all you need to do is cut along the first fold (the one from when you folded the paper in half), but don’t cut through the first or last bit, you need those to hold the ring together

sounds more complicated than it is, you’ll see what I mean when you try for yourself .

In brief –
take a 1/4 piece of paper, and rip off a 1cm strip (not completely – leave a little attached). keep zigzagging like that untill you have a long string. make it into a ring, and then go through it,
