How to clear Python shell?
Python provides a python shell which is used to execute a single Python command and display the result. It is also called REPL. REPL stands for Read, Evaluate, Print and Loop. The command is read, then evaluated, afterwards the result is printed and looped back to read the next command.Sometimes after executing so many commands and getting haphazard output or having executed some unnecessary commands, we may need to clear the python shell. If the shell is not cleared, we will need to scroll the screen too many times which is inefficient. Thus, it is required to clear the python ...
Read MoreDifference between default and static interface method in Java 8.
According to Oracle's Javadocs −Default methods enable you to add new functionality to the interfaces of your libraries and ensure binary compatibility with code written for older versions of those interfaces.A static method is a method that is associated with the class in which it is defined rather than with any object. Every instance of the class shares its static methods.Static method in interface are part of the interface class can’t implement or override it whereas class can override the default method.Sr. No.KeyStatic Interface MethodDefault Method1BasicIt is a static method which belongs to the interface only. We can write implementation ...
Read MoreC++ program to overload addition operator to add two complex numbers
Suppose we have a complex number class with real and imaginary part. We shall have to overload the addition (+) operator to add two complex number. We also have to define a function to return complex number in proper representation.So, if the input is like c1 = 8 - 5i, c2 = 2 + 3i, then the output will be 10 - 2i.To solve this, we will follow these steps −Overload the + operator and take another complex number c2 as argumentdefine a complex number called ret whose real and imag are 0real of ret := own real + real ...
Read MoreC++ Program to Check if all rows of a matrix are circular rotations of each other
The aim of this article is to implement a program C++ program to check if all rows of a matrix are circular rotations of each other. Here is a small glimpse on what a matrix exactly is. The rectangular array of symbols or numbers organized in rows and columns is known as a matrix. A matrix can be of many distinct types, including row, column, horizontal, vertical, square, diagonal, identity, equal, and singular. Addition, subtraction, as well as multiplication are the three fundamental matrix operations. The goal is to determine whether all rows of a matrix of size n*n ...
Read MoreC Program To Write Your Own atoi()
The aim of this article is to implement a program C Program To Write Your Own atoi(). Before we begin, let us take a deeper understanding of what an atoi() function is all about. This will help in writing the program as well as understanding the concepts pretty much easier. To the ones who are not much aware of what an atoi() function is. Here you go. The atoi() function changes a string of elements into an integer value. The string that is entered is a string of characters that has the potential to become a numeric value of the ...
Read MoreMinimize given Number by swapping adjacent digits with odd difference
The aim of this article is to implement a program to minimize a given number by swapping adjacent digits with odd differences. The goal is to determine the lowest amount that can be created from a string of size N indicating an integer using only the characters '1', '2', and '3' by exchanging adjacent characters any number of times. As we all know, a string is a group of characters that ends with the null character "0" in C programming. Characters from the C String are kept in a character array. A C string differs from a character array in ...
Read MoreC++ Program to Find Lexicographically minimum string rotation
The aim of this article is to implement a C++ Program to Find Lexicographically minimum string rotation. Coming on to the definition of string, a string is a group of characters that ends with the null character "0" in C programming. Characters from the C String are kept in a character array. A C string differs from a character array in that it ends with the distinctive character "\0." Finding the rotation of a string that has the lowest lexicographical order among all feasible rotations is known to be the lexicographically minimal string rotation as well as lexicographically smallest circular ...
Read MoreCheck if given String is K-periodic for all K in range [1, N]
The aim of this article is to implement a program to check if a given String is K-periodic for all K in range [1, N]. The aim is to determine whether the supplied string is K-periodic provided the string s and the integer K. If a string repeats the sub-string str[0... k-1], it is said to be k-periodic; for example, the string "ababab" is 2 periods long. Print Yes if the supplied string is k-periodic; otherwise, print No. If a character string can be created by concatenating at least one repeats from another string of length k, it is said ...
Read MoreValidating Indian vehicle number plate using Regular Expression
In this problem, we will validate the Indian vehicle number plate using the regular expression. The regular expression is the search pattern created using the different characters, which we can use to match a particular pattern in the given string. Problem statement - We have given a string representing the Indian vehicle number plate. We need to use the regular expression to validate the given string. Sample Example Input: num1 = "GJ 03 AY 1097" Output: Yes Explanation - The given vehicle number plate is valid. Input: num2 = "TN 1A3 PZ 1287" ...
Read MoreValidating UPI IDs using Regular Expressions
In this problem, we will validate the UPI id using the regular expression. The UPI is the unified payment interface that is given to each customer, and other people can use it to transfer money to you. The UPI id contains alphanumeric characters. The UPI id should always contain a ‘@’ character. The UPI id should not have white spaces. The UPI id may have a dot(.) or hyphen(-). Problem statement − We have given an upi id in the string format. We need to validate the UPI id using the regular expression. Sample Examples Input: upi ...
