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.
