A stack is a data structure that follows the Last In First Out (LIFO) principle.

• Stack is a collection of elements with two main operations: push (adds element) and pop (removes top element)

• Common implementations include using arrays or linked lists

• Example: Undo feature in text editors uses a stack to store previous states

Merge sort is a divide and conquer algorithm that divides the input array into two halves, sorts them recursively, and then merges them back together.

• Divide the input array into two halves

• Recursively sort each half

• Merge the sorted halves back together

• Time complexity is O(n log n)

Optimizing a stack involves reducing unnecessary operations and improving memory usage.

• Implementing tail call optimization to reduce stack space usage

• Using iterative algorithms instead of recursive ones to avoid stack overflow

• Minimizing the number of local variables stored on the stack

• Using dynamic memory allocation instead of fixed-size arrays to optimize memory usage

Use a JOIN statement to combine data from two tables without a common column.

• Use a JOIN statement to combine data from two tables based on a different column

• Specify the columns to select from each table in the query

• Use aliases to differentiate between columns with the same name in different tables

Use SQL query with ROW_NUMBER() function to delete duplicates and keep one.

• Use ROW_NUMBER() function to assign a unique number to each row partitioned by the duplicate column(s)

• Delete rows where the row number is greater than 1

Use Java Stream API to sort a list of employee objects based on a specific field.

• Use the sorted() method of Stream to sort the employee objects based on a Comparator.

• Define a Comparator based on the field you want to sort by.

• Example: List sortedList = employeeList.stream().sorted(Comparator.comparing(Employee::getSalary)).collect(Collectors.toList());

Quick Sort is a popular sorting algorithm that uses a divide-and-conquer approach to sort elements in an array.

• Divides the array into two sub-arrays based on a pivot element

• Recursively sorts the sub-arrays

• Combines the sorted sub-arrays to produce the final sorted array

• Example: [3, 6, 8, 10, 1, 2, 1] -> [1, 1, 2, 3, 6, 8, 10]

Use SQL query with MAX function to get the maximum salary from a table.

• Use SELECT MAX(salary) FROM employees;

• Make sure to replace 'employees' with the actual table name where salary information is stored.

• Ensure that the column name for salary is correct in the query.

Design considerations for front end web applications include user experience, performance, scalability, accessibility, and security.

• Implement security measures such as ...read more

OOP is a programming paradigm based on the concept of objects, which can contain data in the form of fields and code in the form of procedures.

• OOP focuses on creating objects that interact with each other to solve problems

• Encapsulation: Objects can hide their internal state and require interaction through defined interfaces

• Inheritance: Objects can inherit attributes and methods from parent classes

• Polymorphism: Objects can take on different forms or have different behaviors

• Exa...read more
