Amultithreaded web server wishes to keep track of the number of requests it services (known as hits). consider the two following strategies to prevent a race condition on the variable hits. the first strategy is to use a basic mutex lock when updating hits: int hits; mutex lock hit lock; hit lock. acquire(); hits++; hit lock. release(); a second strategy is to use an atomic integer: atomic t hits; atomic inc(& hits); explain which of these two strategies is more efficient.
