What is the Difference Between CSS and SCSS CSS (Cascading Style Sheets) and SCSS (Sass) are two stylesheet languages used to create webpages. CSS is a traditional style sheet language that allows web developers to define how HTML elements appear. SCSS is an extension of CSS that adds features such as variables, nesting and mixins. Both are used to define styling rules for webpages, but SCSS offers more powerful and efficient styling options. 28. A Search Algorithm A Search Algorithm is a process used to find a particular item in a large collection of data. It is a powerful tool that can quickly and accurately locate the desired item in a fraction of the time it would take to manually search through the data. It is used in many applications such as finding a file on a computer, finding a record in a database, or locating a web page. 29. Difference between DELETE and TRUNCATE Delete and Truncate are both used to remove data from tables, but they differ in how they do it. Delete removes rows one at a time while Truncate removes all rows at once. Delete can be used on individual rows, while Truncate can only be used on entire tables. Delete can be used with a WHERE clause to limit the rows that are removed, while Truncate has no WHERE capability. Delete will also log the deleted rows, while Truncate does not. Finally, Delete can be rolled back, while Truncate cannot. 30. Levene's Test in R Programming Levene's Test is a statistical test used to assess the homogeneity of variances in R Programming. It is used to determine whether the sample variances of two or more groups are equal. It is used to check the assumptions of ANOVA, which require that the variances of the populations from which the samples were taken are equal. 31. Python - Difference between two lists Python is a powerful, versatile programming language that is used for web development, data analysis, artificial intelligence and more. It is easy to learn and has a wide range of libraries for data manipulation and visualization. With Python, you can quickly and easily compare and contrast two lists to identify differences in their content. This makes Python a great choice for quick and efficient data comparison. 32. Python OpenCV – waitKey Function Python OpenCV's waitKey function is a powerful tool for creating dynamic visualizations. It takes a single argument, a time in milliseconds, and pauses the execution of a program until a key is pressed. By using this function in combination with other OpenCV functions, complex graphical interfaces can be created that respond to user input. With waitKey, the possibilities are endless. 33. GFact 50: Python End Parameter in Print Python's print statement has an optional end parameter which allows users to specify what should be printed at the end of any given statement. This parameter can be used to indicate the end of a line, or to separate multiple items printed on the same line. By default, Python prints a new line character at the end of each print statement, but the end parameter allows users to customize the output to their exact needs. 34. islower(), isupper(), lower(), upper() in Python and their applications The islower(), isupper(), lower(), upper() functions in Python are used to check case and convert a string to lower or upper case. islower() and isupper() are used to check if a character is in lower or upper case, respectively. lower() and upper() are used to convert a character or string to lower or upper case, respectively. These functions can be used to improve readability of text, for example in titles or headings. 35. SQL Trigger on Student Database A SQL Trigger can be used to automatically execute a specified set of actions when certain conditions are met within a Student Database. It is a stored program that is triggered by certain events, such as inserting, updating or deleting data in a table. Triggers can be used to enforce data integrity, ensure data consistency and enforce business rules. They can also be used to automate complex tasks and provide data security. 36. History of Python Python is a widely used general-purpose, high-level programming language. It was created in the late 1980s by Guido van Rossum and first released in 1991. Python has a design philosophy that emphasizes code readability and a syntax that allows programmers to express concepts in fewer lines of code than in other languages. It is used in a wide variety of applications, including web and software development, data science, and scientific computing. Python is a powerful, versatile language that is popular among developers and data scientists. 37. Searching Algorithms Searching algorithms are an important part of computer science. They are used to find and retrieve data from a given data set. Examples of searching algorithms include linear search, binary search, and hashing. They are used to quickly and efficiently find the data that is being searched for. Searching algorithms are used in many applications and are key to efficient data management. 38. Python Modules Python Modules provide an efficient way to organize and reuse code. They are separate files that can be imported into other Python scripts, allowing users to access functions, classes, and variables without having to recreate them. Modules provide a powerful tool that allows developers to write code more quickly and efficiently. With Python Modules, developers can create reusable, modular code that can be used in a variety of projects and applications. 39. Memory Leak in C and How To Avoid It Memory leaks occur when an application fails to release previously allocated memory, leading to a gradual decrease in available memory. In C, memory leaks can occur when incorrect pointers, incorrect use of malloc()/free(), and not releasing memory allocated with new are not properly handled. To avoid memory leaks, developers should ensure that all memory allocated is freed and that pointers are properly managed. Additionally, using smart pointers and garbage collection can help to prevent memory leaks. 40. Floor and Ceil Function in Python Floor and Ceil functions in Python are used to round numbers down or up respectively. Floor rounds down to the nearest integer, while Ceil rounds up. These functions are useful when dealing with decimal numbers, as they enable precise control of the rounding process. Floor and Ceil can also be used to find the nearest multiple of a number in a given range.
