Binary Search in PHP
Binary search is a search algorithm used to find the position of a target value within a sorted array efficiently. It works by repeatedly dividing the search range in half and comparing the middle element with the target value. How Binary Search Works The binary search algorithm follows these steps − Start with the entire sorted array and set left pointer to first element, right pointer to last element. Calculate the middle index as the average of left and right pointers (integer division). Compare ...
Read MoreCreating multiple process using fork() in C
In this section we will see how to use the fork() system call to create child processes in C. The fork() function creates a new process by duplicating the calling process, allowing both parent and child processes to execute different tasks. When fork() is called, it returns different values to distinguish between processes: a positive value (child's PID) to the parent process, 0 to the child process, and -1 if the fork failed. Syntax #include pid_t fork(void); Note: This program requires a Unix-like operating system (Linux, macOS) to compile and run. The ...
Read MoreGet and Set the stack size of thread attribute in C
To get and set the stack size of thread attribute in C, we use the pthread_attr_getstacksize() and pthread_attr_setstacksize() functions. These functions allow us to query and modify the minimum stack size allocated to a thread's stack. Syntax int pthread_attr_getstacksize(const pthread_attr_t *attr, size_t *stacksize); int pthread_attr_setstacksize(pthread_attr_t *attr, size_t stacksize); pthread_attr_getstacksize() This function retrieves the current stack size from a thread attribute object. It returns 0 on success, otherwise returns an error number. Parameters: attr − Pointer to the thread attribute object stacksize − Pointer to store the retrieved stack size in bytes ...
Read MoreOctal literals in C
In C, we can use octal literals by typing a zero before the actual number. For example, if an octal number is 25, then we have to write 025. Octal literals use base-8 numbering system and contain only digits 0-7. Syntax 0octal_digits Where octal_digits are valid octal digits (0-7). Example The following example demonstrates how to use octal literals in C − #include int main() { int a = 025; /* Octal 25 = Decimal 21 */ int b = ...
Read Morelvalue and rvalue in C
An lvalue (locator value) represents an object that occupies some identifiable location in memory (i.e. has an address). An rvalue is defined by exclusion − every expression is either an lvalue or an rvalue, so an rvalue is an expression that does not represent an object occupying some identifiable location in memory. Syntax lvalue = rvalue; // Valid assignment rvalue = lvalue; // Invalid assignment (compilation error) Example 1: Valid lvalue Assignment An assignment expects an lvalue as its left operand. Here's a valid example − #include int ...
Read MorePHP Program for Converting Roman Numerals to Decimal Lying Between 1 to 3999
Roman numerals are characters used in a numeric notation system based on the ancient Roman system. In this tutorial, we'll convert Roman numeral strings to decimal values in the range 1 to 3999. Roman Numeral System Roman numerals follow descending order but use subtractive notation to avoid four consecutive characters. Here are the main symbols − SYMBOL VALUE M 1000 CM 900 D 500 CD 400 C 100 XC 90 L 50 XL 40 X 10 ...
Read MoreHow to Disable root Login Access to PhpMyAdmin?
PhpMyAdmin is a popular web−based tool for managing MySQL databases through a browser interface. By default, it allows root user login, which grants complete administrative control over the entire database system. While convenient for initial setup, root access poses significant security risks if compromised. Why Disable Root Login Access? The MySQL root user has unrestricted privileges to create, modify, or delete any database, user, or configuration. If an attacker gains root credentials, they can cause irreversible damage or steal sensitive data. Additionally, root accounts are often shared among multiple users, increasing the risk of unauthorized access. Method ...
Read MorePHP Program to Check if all rows of a matrix are circular rotations of each other
A rectangular array called a matrix is made up of rows and columns. And circular rotations entail rotating the array's elements so that after one rotation, the last member is in the first position and the other elements are shifted to the right. We are given an N*N matrix in this problem, and our objective is to determine whether all of the rows are circular rotations of one another. If they are, print "YES, " otherwise print "NO." In order to better understand the issue, let's look at some cases with explanations below. Input 1 mat ...
