Scala & Spark-Master Big Data with Scala and Spark - Solution (For Loop)

The video tutorial guides viewers through writing a program to calculate the factorial of a number. It begins with obtaining user input and converting it to an integer. The tutorial then explains using a for loop to iterate through numbers and perform cumulative multiplication to find the factorial. Debugging tips are provided, emphasizing the importance of initializing variables correctly. The tutorial concludes with verifying the program's output and ensuring it calculates the factorial accurately.
