oh yesh i just noticed...yes it will be 17 ..you are right

yes the decrypted text is different.. its "WOTLD"

No no dea....we do left shift only for remainder that is r1,r2 and r.....and q is the quotient part so we calculate it by by dividing r1/r2....that is 5 both times when we calculate it....i hope you got me ...if you didnt you can reask your doubts...

bro i have tried before keeping cera far away ....it doesn't work as it becomes blur...still thanks for your veru precious feedback...☺

Autofocus turn off and have manually focus on sheet
