Retrieve the second highest salary from an employee table using SQL queries.
Use the 'DISTINCT' keyword to eliminate duplicate salaries.
Utilize 'ORDER BY' clause to sort salaries in descending order.
Apply 'LIMIT' or 'OFFSET' to fetch the second record.
Example SQL query: 'SELECT DISTINCT salary FROM employees ORDER BY salary DESC LIMIT 1 OFFSET 1;'
A Martingale is a mathematical concept used in probability theory and statistics. Markov Processes are stochastic processes that satisfy the Markov property.
A Martingale is a sequence of random variables where the expected value of the next variable, given the current and past variables, is equal to the current variable.
Markov Processes are stochastic processes where the future state depends only on the current st...
Brownian motion is the random motion of particles in a fluid due to collisions with other particles.
Brownian motion was first observed by Robert Brown in 1827.
It is named after the botanist Robert Brown.
The motion is caused by the random movement of fluid molecules.
Brownian motion is a continuous-time stochastic process.
It is often used to model various phenomena in physics, finance, and biology.
Properties of Brow...
Sorting algorithms are methods used to arrange elements in a list in a specific order.
Bubble Sort - compares adjacent elements and swaps them if they are in the wrong order
Merge Sort - divides the list into smaller sublists, sorts them, and then merges them back together
Quick Sort - selects a 'pivot' element and partitions the list into two sublists around the pivot
Insertion Sort - builds the final sorted list one...
