Scala & Spark-Master Big Data with Scala and Spark - For Loop

The video tutorial explains the concept of for loops, highlighting their syntax and functionality. It demonstrates how to write a simple for loop using a range and iterates over it. The tutorial further explores a practical example of calculating a cumulative sum by taking user input and updating a sum variable within a for loop. The video concludes by running the code and verifying the output, emphasizing the flexibility and utility of for loops in programming.
