SQL query to retrieve the second highest marks from a student table using various methods.
Use the 'DISTINCT' keyword to eliminate duplicate marks: SELECT DISTINCT marks FROM student;

Rotating an array involves shifting its elements to the left or right by a specified number of positions.
To rotate an array to the right by k positions, use: `arr = arr[-k:] + arr[:-k]`.
For left rotation, use: `arr = arr[k:] + arr[:k]`.
Example: For arr = ['a', 'b', 'c', 'd'] and k = 2, right rotation gives ['c', 'd', 'a', 'b'].
In Python, you can also use `collections.deque` for efficient rotations.
Reversing an array involves swapping elements from both ends towards the center.
Use a loop to iterate from the start to the middle of the array.
Swap the elements at the current index and its corresponding index from the end.
Example: For array ['a', 'b', 'c'], after reversing it becomes ['c', 'b', 'a'].
FRD (Functional Requirements Document) outlines system functionalities; BRD (Business Requirements Document) details business needs.
FRD specifies how the system should behave, e.g., user login features.
BRD focuses on the business objectives, e.g., increasing user engagement.
FRD is often technical, while BRD is more high-level and strategic.
Both documents are crucial for project success and stakeholder alignment.
