Emotion identification or recognition is the ability of a person or an object to sense a particular emotion exhibited in the environment and place it into one of the many categories of emotions. Emotion Classification in python is a feasible alternative to the traditional sentiment analysis technique which labels words or sentences as positive or negative and allots them with a polarity score accordingly. The basic ideology behind this algorithm is to mimic the human thought process and it tries to segment the words portraying emotions from the text. The analysis is performed with a training set of data where ... Read More

In this article, we will delve into a specific aspect of string handling in C++: the string::npos constant. string::npos is a static member constant value with the greatest possible value for an element of type size_t. This constant is defined with a value of -1, which, when cast to size_t, gives us the largest possible representation for size_t. In the context of strings in C++, it is generally used to indicate an invalid position. What is String::npos? In C++, string::npos is a constant static member of the std::string class that represents the maximum possible value for the size_t type. It ... Read More

Whether you are a beginner or an intermediate Python programmer, this guide will offer the knowledge and skills necessary to use Python's powerful features in text manipulation. Problem Statement Given a sentence, our task is to find the smallest word. The "smallest" word refers to the word with the fewest characters. In case of a tie, we'll return the first occurring smallest word. Approach We start by splitting the sentence into words, which we'll accomplish by using spaces as the ... Read More

In this article, we will discuss how to modify a given string in C++ by rearranging the vowels in alphabetical order at their respective indices. We will also explain the approach used to solve this problem and provide an example with a test case. Problem Statement Given a string, rearrange the vowels in alphabetical order at their respective indices. The consonants in the string should remain in their original order. For example, given the string "tutorialspoint", the output should be "tatiriolspount". Approach The problem can be solved using a simple algorithm. We can first create a separate string that contains ... Read More

A common task when working with strings is to make sure that a string adheres to certain conditions. One of these conditions could be to ensure that every substring of length K in the string contains unique characters only. This is a frequent requirement in problems related to data encoding, string manipulation, and cryptography. Problem Statement The problem we are trying to solve can be stated as follows − Given a string str and an integer K, modify the string by inserting characters such that every substring of length K in the string contains unique characters only. Proposed Solution We ... Read More
