Please use C$++$ langague, Please do not motify the code, just add code use binary semaphores instead of mutex locks, Use the following description: $$We have five lawyers, each lawyer needs two chopsticks to eat. The code creates $5$ threads, one per lawyer, and it has five binary semaphores to represent the chopsticks. use sleep$(1)$ in the code to allows all threads $($lawyers$)$ to grab the chopstick on their left before the one on their right. Then $,$ use the sleep$(2)$ in the code to represent the time taken for eating!$$
