Unit 2 Session 2 (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: Check if the candidate is already in the dictionary, add them if not, then increment their votes by 1.

1) If the candidate is a key in the dict, increment the value by 1 2) Otherwise, map candidate -> 1 in the dict

I-mplement

def cast_vote(votes, candidate): if candidate in votes: votes[candidate] += 1 else: votes[candidate] = 1 return votes

Alternative Solution

def cast_vote(votes, candidate): if candidate not in votes: votes[candidate] = 0 votes[candidate] += 1 return votes
