In this article, we will learn a python program to check if a matrix is lower triangular. Assume we have taken an input matrix. We will now check whether the input matrix is lower triangular using the below methods. Methos Used The following are the various methods to accomplish this task − Using nested for loop What is a Lower Triangular Matrix? If all the entries above the main/principal diagonal are zero, a square matrix is said to be lower triangular. Example 1 0 0 0 2 3 0 0 1 3 7 0 0 ... Read More

In this article, we will learn a Python program to check if a number is a Perfect Square in a List. What is a Perfect Square? A perfect square is an integer that can be written as the square of another integer. It is referred to as the product of some integer with itself in other words. Example 25 = 5x5 Methods Used The following are the various methods to accomplish this task − Using List comprehension & math module Using For Loop & math module Using ** Operator Using the filter() and lambda functions The sqrt() ...

In this article, we will learn a python program to check if a matrix is symmetric. What is a Symmetric Matrix? If the transpose of a square matrix matches the original matrix, the matrix is said to be symmetric. By changing from row to column and from column to row, the symmetric matrix may be obtained. For Example 2 6 8 6 1 3 8 3 9 Assume we have taken an NxN input matrix. We will now check whether the matrix is symmetric or not using the below methods. Methos Used The following ... Read More

In this article, we will learn a Python Program to calculate Profit Or Loss. The following are the different methods to accomplish this task − Using If Conditional Statements Using the abs() function. What are the selling price, cost price, and Profit and Loss? The price a consumer pays to purchase a product or a commodity is known as the selling price. It is a price that is higher than the cost price and also includes a portion of the profit. Cost price is the cost at which the seller buys the product or the commodity. He ... Read More

In this article, we will learn how to break a Set into a list of sets in Python. Assume we have taken an input set. We will now break this input set into a list of sets element-wise using the below-mentioned methods. Methods Used The following are the various methods used to accomplish this task − Using For Loop and append(), add() functions Using Python map() & lambda functions Using List Comprehension Method 1: Using For Loop and append(), add() Functions Algorithm (Steps) Following are the Algorithms/steps to be followed to perform the desired task. − Create ...

In this article, we will learn how to add a data table to the figure using Python. Although matplotlib is primarily a plotting library, it also assists us with minor tasks when making a chart, such as having a nice data table alongside our attractive visuals. It is critical to understand why we are adding a table to a plot. The primary goal of plotting data visually is to clarify the otherwise incomprehensible (or barely understandable) data values. Now we want to add the data back in. It is not advisable to just put a large table with values beneath ... Read More

This tutorial will help us to read an integer number from the user. The user is prompted to enter any integer number. Then the entered integer is displayed to the console. Method 1: Using read and getLine function This approach uses the read and getLine function to attempt to parse the input as an integer and display the integer number to the console. Algorithm Step 1 − main :: IO () is defining the main function. Step 2 − putStrLn "Enter an integer: " prints the message asking for the user input. Step 3 − input

This tutorial will help us to find the 1's complement of the given number. The 1's complement of a binary number is found by inverting each bit of the number. A 1 becomes a 0, and a 0 becomes a 1. This is also known as the bitwise NOT operation. The 1's complement of a number can be useful in certain types of error-detecting and error-correcting Example:s, as well as in certain types of digital logic circuits. The most common use of 1's complement is in signed number representation where it's used to represent negative numbers. For example, if the ... Read More

This tutorial will help us to find the power of a number using library function. The base value and the exponent value is passed as an argument that is used to find the exponent power of the base value passed. And the final output is displayed. For example, For base = 2 ; exponent = 3, it would return 8. Syntax power x y = product (replicate (fromInteger y) x) Product function computes a product of all elements in the list power x y = foldl (*) 1 (replicate (fromInteger y) x) Foldl takes the first item with ...

This tutorial will help us in reading the height of a person and printing if the person is taller, dwarf or average height person on being compared. The height value (in centimeters) is passed as argument to the function defined and then the height is being compared with the condition defined in Haskell. And the final output is displayed. Algorithm Step 1 − Program execution will be started from main function. The main() function has whole control of the program. Step 2 − Create user defined function to perform the task Step 3 − The if-else statement is defined ... Read More
