Load testing measures system performance under expected conditions, while stress testing evaluates limits under extreme conditions.
Load testing simulates expected user load, e.g., 1000 users accessing a website simultaneously.
Stress testing pushes the system beyond its limits, e.g., 5000 users to see how it handles overload.
Load testing helps identify performance bottlenecks under normal conditions.
Stress testing ...
In my project, we utilize OOP concepts like encapsulation, inheritance, polymorphism, and abstraction for robust software design.
Encapsulation: We use classes to bundle data and methods, ensuring data hiding. Example: A 'User' class with private attributes.
Inheritance: We create a base class 'Animal' and derive 'Dog' and 'Cat' classes to reuse code and extend functionality.
Polymorphism: We implement method overrid...
Program in Python to remove duplicates from an array of strings.
Use a set to store unique elements
Iterate through the array and add each element to the set
Convert the set back to a list to remove duplicates
Program for regex

- Ans.
To find the middle element of a linked list, use the slow and fast pointer approach.
Initialize two pointers, slow and fast, both pointing to the head of the linked list.
Move the slow pointer by one step and the fast pointer by two steps until the fast pointer reaches the end of the list.
The element pointed to by the slow pointer at this point will be the middle element of the linked list.

- Q2. Insert and delete in linked list
- Ans.
Inserting and deleting nodes in a linked list involves updating pointers to maintain the list's structure.
To insert a node, update the next pointer of the new node to point to the current node's next, then update the current node's next pointer to the new node.
To delete a node, update the next pointer of the previous node to skip over the node to be deleted, then free the memory of the deleted node.
