Let me walk you through your first real programming problem. You'll read two integers from input and print their sum. This problem tests whether you understand variable declaration, input operations, and basic arithmetic.
I'll show you how to break down a simple problem into steps. You need to declare two variables, read values into them, compute their sum, and output the result. Each step uses concepts from this part.
You can practice this on Codeforces using the link below. The problem gives you two integers on a single line, and you output their sum. Try solving it yourself before reading the next units.
