A lightweight Go utility that calculates the arithmetic series (the sum of all integers) from zero up to a user-defined limit. 🚀 How it Works
The program prompts the user for a "favorite number" via the terminal. It then iterates through every integer from 0 up to (but not including) that number, accumulating the total.
Mathematically, this represents the summation:
j=0∑n−1j
🛠 Features
Interactive Input: Uses fmt.Scan to capture user data at runtime.
Input Validation: Basic error handling to ensure only integers are processed.
Clean Scope: Demonstrates the use of local variables and function return values to avoid "side effects."
