Break/Continue in a Nested Loop

Let's apply the concepts of break and continue to analyze travel costs practically. We'll combine a while loop and a for loop to process expenses across multiple trips.

Example: `break` in Mixed Nested Loops

Imagine you have multiple trips, and each trip has a list of expenses. If any expense exceeds a specific budget threshold, we will stop processing that trip immediately.


              123456789101112131415161718192021222324
            
# List of trips with their respective expenses
travel_costs = [
    [100, 150, 300, 50],   # Trip 1
    [200, 500, 100, 80],   # Trip 2
    [120, 180, 400, 150]   # Trip 3
]

# Budget threshold
budget = 200

# Outer while loop to iterate through trips
i = 0
while i < len(travel_costs):
    print(f"Processing expenses for Trip {i + 1}:")
    
    # Inner for loop to iterate through expenses
    for cost in travel_costs[i]:
        if cost > budget:  # If expense exceeds the budget, stop processing the current trip
            print(f"Expense {cost} exceeds the budget. Stopping this trip.")
            break
        print(f"Expense: ${cost}")
    
    i += 1  # Move to the next trip
    print("")  # Add a new line for readability

How does the code work?

Find the First Significant Expense Write a program to:

Iterate through each trip's expenses.
Stop at the first significant expense greater than $200 using break.
Skip expenses less than $100 using continue.
