## Description

You are on a flight and wanna watch two movies during this flight.

You are given int[] movie_duration which includes all the movie durations.

You are also given the duration of the flight which is d in minutes.

Now, you need to pick two movies and the total duration of the two movies is less than or equal to (d - 30min).

Find the pair of movies with the longest total duration. If multiple found, return the pair with the longest movie.

``````e.g.
Input
movie_duration: [90, 85, 75, 60, 120, 150, 125]
d: 250
``````
``````[90, 125]
90min + 125min = 215 is the maximum number within 220 (250min - 30min)
``````

## Solution

``````def solution(movies, duration):
if duration <= 30:
return []
objective = duration - 30
# If same one is occur, longest first, then let's find longest first
# List ascending order
movies.sort(reverse=True)
for i in range(0, len(movies) - 2):
for j in range(i + 1, len(movies) - 1):
if cur_answer_list + movies[j] <= objective:  # Got ya!
break

if __name__ == "__main__":
movie_duration = [90, 85, 75, 60, 120, 150, 125]
d = 250
print(solution(movie_duration, d))

``````

## Short Description

• Approach
• At first, I think I need to sort the given list to select largetst movie duration (since the condition is longest movie is required if same answer exists, that is why the if condition `sum(answelsr_movies) < sum(cur_answer_list)` does not contain euqal sign)
• From the largest one, pick and traverse the list to find less than objective, which is duration - 30.
• When the loop found solution, we need to keep at moment to find whether there is another solution more closer to duration.
• If all loop are traversed, the final list is solution.
