Unit 2 Session 1 (Click for link to problem statements)

U-nderstand

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

P-lan

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Create and fill a dictionary using two lists as the keys and values.

1) Create an empty dictionary
2) For each index in the keys/values lists
  a) Get the key from the keys list at that index
  b) Get the value from the values list at that index
  c) Add the key:value pair to the new dictionary
3) Return the new dictionary

⚠️ Common Mistakes

• If you just loop through elements in either list, it gets tricky to make sure you are matching their indices. Instead, try constructing your loop to iterate over each index.
