The problem statement includes finding the sum of range in a series of first odd numbers then even natural numbers up to N. The sequence consists of all the odd natural numbers from 1 to N and then all the even natural numbers from 2 to N, including N. The sequence will be of size N. We will be provided with a range in the problem for which we need to find out the sum of the sequence within that range, a and b i.e. [a, b]. Here a and b are included in the range. For example, we are ... Read More

The problem statement includes printing the sum of product of consecutive binomial coefficients for any positive number, N which will be the user input. The positive coefficients in the binomial expansion of any term are called binomial coefficients. These binomial coefficients can be found out using Pascal's triangle or a direct formula. The formula to calculate the binomial coefficient: $$\mathrm{^nC_{r}=\frac{n!}{(n-r)!r!}}$$ where, n and r can be any positive numbers and r should never be greater than n. Note : The value of 0! is always equal to 1. In this problem, we will be given a positive number N and ... Read More

Creating a list centered on zero involves generating a sequence of numbers where zero is positioned in the middle of the list. While the size of the list can be customized, it is often preferred to use an odd number to ensure symmetrical distribution of elements around zero. In this article, we will discuss the different approaches to creating a list centered on zero using Python programming. Approach We can follow the below steps to create a centered list − Determine the desired size of the list. Let's call this value n. If n is an odd number, it ... Read More

Strings in Python can contain any sequence of characters, including letters, numbers, symbols, and whitespace. It can represent text, numbers, or any other type of data that can be represented as a sequence of characters. In Python, strings are enclosed in single quotes ('') or double quotes (""). Multiline strings can be created using triple quotes (''' or """). Here are a few examples of valid Python strings: "Hello, World!" "12345" "Python is awesome!" Counting the number of characters in a string involves determining the total count of individual characters within the string. Python offers various techniques for ... Read More

The problem statement includes printing the sum of digits of N, which will be the user input, when written in different bases from 2 to N−1. In this problem, we will be provided any positive integer N and we need to represent that number in a different base numeral system from 2 to N−1 and find the sum of the digit of each different base numeral system. In the base−n numeral system, every digit of the representation of any number in that numeral system from right represents the number of times power of n from 0 to 31. For example, ... Read More

A meter is the fundamental unit of length in the International System of Units (SI) and is used worldwide. It is defined as the length of the path traveled by light in a vacuum during a time interval of 1/299, 792, 458 of a second. Meters are commonly used in scientific, engineering, and everyday contexts. The yard, on the other hand, is a unit of length commonly used in both the British imperial and US customary systems of measurement. It is an English unit defined as 3 feet or 36 inches. It is defined as exactly 0.9144 meters. Yards are ... Read More

When working with text processing and analysis tasks, it is frequently required to count the vowels, lines, and characters in a text file. The goal is to determine the total counts of vowels, lines, and characters present in the file. Python provides various methods and techniques that can be used to accomplish these counting tasks effectively and efficiently. In this article, we will discuss different approaches for counting vowels, lines, and characters in a text file using Python programming. Approach By following the below steps, we can effectively count the vowels, lines, and characters in a text file using Python. ... Read More

The problem statement includes printing the sum of bitwise OR of all possible subsets of a given set. A set is a collection of data of similar type. A subset of any set is a set containing few elements of the set or all the elements of the given set. The number of subsets of any set is given by $\mathrm{2^{n}−1}$, where n is the number of elements in the given set. For example, a={1, 2, 3, 4, 5} is the given set. {1}. {2, 3}, {1, 2, 3, 4} and so on are called subsets of a, as they ... Read More

When working with text processing and analysis tasks, it is often necessary to count the words in a text file. The objective is to determine the total number of words present in the file. Python offers several modules and functions that can efficiently and effectively perform word-counting tasks. In this article, we will explore different approaches to obtaining the total word count from a text file using Python programming. Approach Following are the steps to count words in a text file − Open the text file − Use the open() function to open the text file in read mode. ... Read More

The problem statement includes printing the sum of the series whose Nth term is given. The value of N will be given in the input. We need to find the sum of the sequence up to N where the Nth term of the sequence is given by: $$\mathrm{N^{2}−(N−1)^{2}}$$ Let’s understand the problem with the below examples: Input N=5 Output 25 Explanation − The value of N given is 5.The first 5 terms of the sequence are: $\mathrm{N=1, 1^{2}−(1−1)^{2}=1}$ $\mathrm{N=2, 2^{2}−(2−1)^{2}=3}$ $\mathrm{N=3, 3^{2}−(3−1)^{2}=5}$ $\mathrm{N=4, 4^{2}−(4−1)^{2}=7}$ $\mathrm{N=5, 5^{2}−(5−1)^{2}=9}$ The sum of the terms of the sequence until 5th ...
