A multithreaded 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.

Write a function called checkfactor that takes two arrays of positive numbers, firstnumberrow and secondnumberrow. checkfactor checks if the first entry in firstnumberrow is divisible by the first entry in secondnumberrow, and performs the same operation on the next array elements until all entries have been checked. all the numbers are positive and the number of entries in the arrays are the same. the function should return the identified divisible numbers in two row arrays named firstdivisible and seconddivisible.restrictions: branches or loops should not be used. the code must use the internal mod and logical functions.hint: the mod function should be used to determine if two numbers are divisible. ex: for num1 and num2 if mod(num1,num2) is 0, then the two numbers are divisible.this is matlab
