Function Overloading in PHPFunction overloading is a feature that permits making creating several methods with a similar name that works differently from one another in the type of the input parameters it accepts as arguments.ExampleLet us now see an example to implement function overloading− Live DemoOutputThis will produce the following output−9.42648Function Overriding in PHPIn function overriding, the parent and child classes have the same function name with and number of argumentsExampleLet us now see an example to implement function overriding− Live DemoOutputThis will produce the following output−Base class function! Base class function declared final! Derived class function! Base class function declared final!Read More
The randomized meldable heap(also called as Meldable Priority Queue) supports a number of common operations. These are known as insertion, deletion, and a searching operation, findMin. The insertion and deletion operations are implemented in terms of an additional operation specific to the meldable heap, Meld(A1, A2).MeldThe basic target of the meld (also called as merge) operation is to take two heaps (by taking each heaps root nodes), A1 and A2, and merges them, returning a single heap node as a result. This heap node is the root node of a heap containing all elements from the two subtrees rooted at ... Read More
What is Assembly Tolerance Stack up Analysis?In short, assembly tolerance stacks up analysis is defined as the tolerance value of the whole assembly or a specific gap of the assembly when we are aware about the tolerance values of all its components.Assembly tolerance chain stack up analysis can be accomplished in different ways. The simplest procedure is termed as the worst case method, which we discuss here.Discussion about Worst Case Method of Assembly Tolerance Stack UpLet, we have an assembly of four thick sheets like below −The thickness and tolerance of the four sheets are displayed in the above figure. ...

In this tutorial, we are going to discuss the string method str.casefold(). It doesn't take any arguments. The return value of the method is a string that is suitable for the caseless comparisons.What are caseless comparisons? For example, the german lower case letter ß is equivalent to ss. The str.casefold() method returns the ß as ss. It converts all the letters to lower case.Example Live Demo# initialising the string string = "TUTORIALSPOINT" # printing the casefold() version of the string print(string.casefold())OutputIf run the above program, you will get the following result.tutorialspointLet's see the example where caseless comparison works. If you directly compare ... Read More
Definition and importance of Tolerance AnalysisTolerance analysis is the term given to a number of processes used to calculate the overall variation and effect of variation on products stemming (i.e. arisen) from imperfections in manufactured parts.Tolerance analysis is performed by product design engineers as they prepare to components for manufacturing. This is done to ensure according to end users’ demand as well as guarantee so that all manufactured components are fitted together within an assembly.The Definition of Tolerance AnalysisTolerance analysis is defined as the general term for activities related to the subject of potential collected variation in mechanical parts and assemblies. ...

A global variable can be accessed in any part of the program. However, in order to be modified, a global variable must be explicitly declared to be global in the function in which it is to be modified. This is accomplished, conveniently enough, by placing the keyword GLOBAL in front of the variable that should be recognized as global.ExampleThe code is as follows wherein we can see how to declare a global variable in PHP− Live DemoOutputThis will produce the following output−Value = 2ExampleLet us now see another example− Live DemoOutputThis will produce the following output−5
We have a method called astype(data_type) to change the data type of a numpy array. If we have a numpy array of type float64, then we can change it to int32 by giving the data type to the astype() method of numpy array.We can check the type of numpy array using the dtype class. Let's check the data type of sample numpy array.Example# importing numpy library import numpy as np # creating numpy array array = np.array([1, 2, 3, 4, 5]) # printing the data type of the numpy array print(array.dtype)OutputIf you run the above code, you will get the ...

Matrix MultiplicationNow procedure of Matrix Multiplication is discussed. The Matrix Multiplication can only be performed, if it satisfies certain condition. Suppose two matrices are P and Q, and their dimensions are P (a x b) and Q (z x y) the resultant matrix can be found if and only if b = x. Then the order of the resultant matrix R will be (m x q).AlgorithmmatrixMultiply(P, Q): Assume dimension of P is (a x b), dimension of Q is (z x y) Begin if b is not same as z, then exit otherwise define R matrix as (a ...

We have given an array of elements, and we have to make them all equal by incrementing the elements by 1. We are allowed to increment n - 1 element at each step. Our goal is to calculate the total number of operations required to make all the array elements equal.For example, if you take the list [1, 2, 3], it took three operations to make all the elements equal. One solution to the problem is. Find the most significant number at each step and increment the rest of the elements by 1. Let's write the code.Example Live Demodef main(): ... Read More
To compare two dates in PHP, the code is as follows. Here, we have used the equality operator to compare dates −Example Live DemoOutputThis will produce the following output−Date1 = 2019-10-30 Date2 = 2019-10-30 Both the dates are equal!ExampleLet us now see another example− Live DemoOutputThis will produce the following output−Date1 = 2019-11-08 Date2 = 2018-08-10 DateOne is the latest date!
