So, now value of rc is 5. Now, if any of the readers go to database part, they will not execute down(db) statement because rc is not 1. Now, one writer can also go in database. So, option B is true. But I am not able to find deadlock here. 1 votes 1 votes jatinmittal199510 commented Feb 1, 2017 reply Follow Share @Lucky Thank you. 1 votes 1 votes Please log in or register to add a comment.
