U-nderstand

Understand what the interviewer is asking for by using test cases and questions about the problem.

• Will the list always contain only numbers?
  • Yes.
• Can the list be empty?
  • Yes.

P-lan

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Loop through a list, and generate a new list containing each element + 1.

1) Create a function with parameters for the list
2) Make an empty list to store the results
3) Loop through the input list
  a) For each element, add the element + 1 to the results list
4) Return the results list
