Tkinter is a standard library in Python which is used for GUI application. Tkinter has various controls which are used to build a GUI-based application.To install Tkinter, we need Python pre-installed. Tkinter actually comes along when we install Python. While installing Python, we need to check the td/tk and IDLE checkbox. This will install the tkinter and we need not install it separately.However, if we missed installing Tkinter while installing Python, we can do it later using the pip command.Step 1 − Make sure Python and pip is preinstalled on your systemType the following commands in command propmt to check ...

What is ISC? The full form of ISC is Indian School Certificate. ISC is an examination which is conducted by CISCE for students of class 12 all over India. ISC exam is similar to the exam of class XII conducted by ICSE. The exam has been made valid by the government of India and other countries. Students who have completed their high school are eligible to take this exam which is conducted by the Council for the Indian School Certificate Examination (CISCE). CISCE is an independent and non-government board of India. UGC (University Grants Commission) and the government of India ... Read More
The C++ STL (Standard Template Library) is a powerful set of C++ template classes to provide general-purpose classes and functions with templates that implement many popular and commonly used algorithms and data structures like vectors, lists, queues, and stacks.It is a library of container classes, algorithms, and iterators. It is a generalized library and so, its components are parameterized. Working knowledge of template classes is a prerequisite for working with STL.Templates are a feature of the C++ programming language that allows functions and classes to operate with generic types. This allows a function or class to work on many different ... Read More
Write a Python code to find price column value between 30000 to 70000 and print the id and product columns of the last three rows from the products.csv file. Result for price column value between 30000 to 70000 and id and product columns last three rows are − id product 79 80 Truck 81 82 Bike 98 99 TruckSolution 1 Read data from products.csv file and assign to dfdf = pd.read_csv('products.csv ')Apply pandas slicing to access all rows of price column between 30000 to 50000 as, df[df.iloc[:, 4].between(30000, 50000)Save the above result to df1Apply slicing to access last ...

In this article, we are given an array arr[] of N integers. Our task is to find the Maximum Sum Decreasing Subsequence in C++. A Maximum Sum Decreasing Subsequence (MSDS) is a subsequence of a given sequence of array. Here the sequence elements are ordered in decreasing arrangement and the sum of these elements is the highest. Here, given a sequence of array a1, a2, …, an, the goal is to find a subsequence ai1, ai2, …, aik, where i1>i2>…>i1, such that we say the subsequence is ai1>ai2>…>aik (ordered in a decreasing order). The sequence of terms ai1+(ai2)...+(aik) is ... Read More
In this article, we are given a number N. Our task is to create a program to find the maximum sum of distinct numbers with LCM as N in C++. To achive this first of all we need to find the sum of maximum numbers that have N as the Lowest Common Multiple (LCM). For better understanding Let us go through 3 key concepts − Least Common Multiple (LCM): The lowest common multiple(LCM) of two or more integers is the smallest positive integer that is divisible for all of the integers. For example, the LCM of 4 and 5 ... Read More
In this article, we are given a string representing a number. Our task is to create a program in C++ to find the maximum sum and product of M consecutive digits from the given number. We find all sequences of M consecutive digits and return the maximum sum and product. In mathematics, consecutive numbers are defined as those numbers that follow each other in increasing order from the smallest to the largest, with no missing numbers in between. This problem can be iterated through the string representation of the number, in other words, we consider consecutive segments of the length ... Read More
In this article, Our task is to create a Program to find the common ratio of three numbers in C++. The common ratio of three numbers is usually the same ratio between two numbers multiplied by each other to get the next one. When a particular number of terms in progression or sequence are involved such as in the geometric progression, a common ratio can be easily found by dividing the term with the preceding term. For instance, if we have three numbers x, y, and z. then the common ratio r can be found as r = x:y = ... Read More
In this article, we are given a number n that denotes the nth term of the series. Our task is to create a Program to find sum of series 1 + 2 + 2 + 3 + 3 + 3 + .... + n in C++. This series is different from the other because it include terms that are repeated according to their values. The series 1 + 2 + 2 + 3 + 3 + 3 + … + n consists of repeated terms that are repeated infinitely only by their value. Such illustration 1 comes once, ’2 twice’, ... Read More
