## Hints and Guidelines

We can solve the problem with summing up numbers in the following way:

• We read the input number n.
• We initially start with a sum sum = 0.
• We run a loop from 1 to n. On each step of the loop, we read the number num and add it to the sum sum.
• Finally, we print the calculated amount sum.

Below is the source code for the solution:
