Welcome to our new series of padlock code breaking challenges.
For each of these challenges you will need to write a computer program to work out the padlock code (3-digit number). Your program will need to output the solution of the given hint. You will then be able to input this combination onto the padlock to see if it unlocks it!
code = 1 + 2 + 3 + 4 + … + 38 + 39 + 40
Use the trinket below to write a program to solve the above hint.
