To obtain minimum value of a function without using derivatives, use methods like bisection, golden section search, or simulated annealing.
Bisection method involves repeatedly dividing the interval in half and checking which half contains the minimum value.
Golden section search is similar to bisection but uses a fixed ratio to divide the interval.
Simulated annealing is a probabilistic method that randomly explores the
To define 3D array in MATLAB or Python, use array indexing. To obtain maximum from matrix elements, use max() function.
In MATLAB, use array indexing with three dimensions: A(x,y,z)
In Python, use numpy library to create 3D array: np.array([[[1,2],[3,4]],[[5,6],[7,8]]])
To obtain maximum from matrix elements, use max() function: max(A)
In Python, use np.max() function to obtain maximum from matrix elements
To get the median of a data sequence, sort the data and find the middle value.
Sort the data sequence in ascending or descending order
If the sequence has an odd number of values, the median is the middle value
If the sequence has an even number of values, the median is the average of the two middle values
Example: For the sequence [3, 1, 4, 2, 5], sort it to [1, 2, 3, 4, 5] and the median is 3
Example: For the sequence [3,...

Recursion is a process in which a function calls itself. Inheritance is a mechanism in OOP where a class inherits properties of another class. Heap is a region of memory used for dynamic memory allocation.
Recursion can be used to solve problems that can be broken down into smaller sub-problems.
Inheritance allows for code reuse and helps in creating a hierarchy of classes.
Heap is used for dynamic memory allocation in la...
There are three types of machine learning: supervised, unsupervised, and reinforcement learning.
Supervised learning involves labeled data and predicting outcomes based on that data.
Unsupervised learning involves finding patterns in unlabeled data.
Reinforcement learning involves an agent learning to make decisions based on rewards and punishments.
Examples of supervised learning include image classification and spam filt...
OOPs stands for Object-Oriented Programming. It is a programming paradigm that uses objects to design applications.
OOPs is based on the concept of classes and objects
It focuses on encapsulation, inheritance, and polymorphism
It helps in creating modular, reusable, and maintainable code
Examples of OOPs languages are Java, C++, Python, etc.
SDLC stands for Software Development Life Cycle, a process used to design, develop, and maintain software.
SDLC is a structured approach to software development
It involves several phases such as planning, analysis, design, implementation, testing, and maintenance
Each phase has its own set of activities and deliverables
SDLC helps ensure that software is developed efficiently, on time, and within budget
Examples of SDLC mo

Swap two numbers with and without temporary variable
Without temporary variable: Use addition and subtraction
With temporary variable: Use a third variable to store the value of one of the numbers
Example without temporary variable: a=5, b=7; a=a+b; b=a-b; a=a-b;
Example with temporary variable: a=5, b=7; temp=a; a=b; b=temp;
