Find pair of elements in an array whose sum is equal to a given number K.
Iterate through the array and for each element, check if K minus the element exists in the array.
Use a hash table to store the elements and their indices for faster lookup.
If multiple pairs exist, return any one of them.
If no pair exists, return null or an appropriate message.
Session is maintained using session affinity or sticky sessions.
Session affinity ensures that a user's session is always directed to the same server.
Load balancer uses a unique identifier to route requests to the same server.
Sticky sessions can be implemented using cookies or URL rewriting.
Session replication can also be used to maintain session data across multiple servers.
Singleton pattern ensures only one instance of a class is created and provides a global point of access to it.

There are three types of errors in PHP: syntax errors, runtime errors, and logical errors.
Syntax errors occur when the code is not written correctly, such as missing semicolons or parentheses.
Runtime errors occur during the execution of the code, such as trying to access an undefined variable.
Logical errors occur when the code runs without errors, but produces unexpected results, such as a miscalculation in a formula.
Session in PHP allows to store user data on the server for later use.
Session starts when a user logs in and ends when the user logs out or the session expires.
Session data is stored on the server and identified by a unique session ID.
Session variables can be set and accessed using the $_SESSION superglobal array.
Session can be destroyed using the session_destroy() function.
Session can be used to store user-specific dat...

Given a string of consecutive nonnegative integers with one missing number, find the missing integer.
Iterate through the string to find the missing number by checking the consecutive integers.
If there is more than one missing number, all integers are present, or the string is invalid, return -1.
Handle cases where the missing number is at the beginning or end of the sequence.
Consider edge cases such as single-digit numb

Different types of errors in PHP include syntax errors, runtime errors, and logical errors.
Syntax errors: Occur when there is a mistake in the code syntax, preventing the script from running.
Runtime errors: Happen during script execution, such as division by zero or calling a function that does not exist.
Logical errors: Difficult to detect as the code runs without errors, but produces incorrect results.
Fatal errors: St...
Session management in PHP involves storing user data on the server to maintain state between multiple requests.
Sessions are started using session_start() function in PHP.

Sessions can be destroyed using session_destroy() function.

The goal is to prevent race conditions and ensure mutual exclusion.
Solutions include using locks, semaphores, and mutex to control access to critical sections.
