TIP102 Unit 3 Session 2 Standard (Click for link to problem statements)
Understand what the interviewer is asking for by using test cases and questions about the problem.
points
where each element represents the number of points available at a festival booth.Plan the solution with appropriate visualizations and pseudocode.
General Idea: Use a stack to simulate the process of collecting points from each booth. Each point value is pushed onto the stack and then immediately popped, adding to the total points collected.
1. Initialize an empty stack and a variable `total_points` to track the sum of points collected.
2. Iterate through the list `points`:
1. Push the current point value onto the stack.
2. Pop the value from the stack and add it to `total_points`.
3. Return the value of `total_points` after processing all booths.
⚠️ Common Mistakes
total_points
variable correctly.def collect_festival_points(points):
stack = []
total_points = 0
for point in points:
stack.append(point)
total_points += stack.pop()
return total_points
# Example usage
print(collect_festival_points([5, 8, 3, 10])) # Output: 26
print(collect_festival_points([2, 7, 4, 6])) # Output: 19
print(collect_festival_points([1, 5, 9, 2, 8]))# Output: 25
