If we can lock a file, we can solve the race condition problem by locking a file during the check-and-use window, because no oth

er process can use the file during the time window. Why don’t we use this approach to solve the race condition problems discussed in this chapter?

Answer:

A file can only be locked out to other users or processes only if it's already open, meaning it's in use as a resource during the time window and therefore it's impossible solving the race condition problem by locking the file during the check-and-use window.

Hence, during the check-and-use process, it's impossible to lock a file.

In conclusion, any lock created can be ignored by the malicious process.

Implement a sublinear running time complexity recursive function in Java public static long exponentiation (long x, int n) to ca
Charra [1.4K]

Answer:

Following are the code block in the Java Programming Language.

//define recursive function

public static long exponentiation(long x, int n) {

//check the integer variable is equal to the 0.

if (x == 0) {

//then, return 1

return 1;

}

//Otherwise, set else

else {

//set long data type variable

long q = exponentiation(x, n/2);

q *= q;

//check if the remainder is 1

if (n % 2 == 1) {

q *= x;

}

//return the variable

return q;

}

}

Explanation:

<u>Following are the description of the code block</u>.

  • Firstly, we define the long data type recursive function.
  • Then, set the if conditional statement and return the value 1.
  • Otherwise, set the long data type variable 'q' that sore the output of the recursive function.

<h2>Explanation:</h2>

There are a lot of cases where people pretend to call from the banks where the receivers have the account.
