Design greedy minimum platforms
for train scheduling
Analyze the design greedy minimum platforms for train scheduling.
Examples
Example 1
Input:
"test_input_1"
Output:
"output_1"
Example 2
Input:
"test_input_2"
Output:
"output_2"
Hints
Hint 1
Consider sorting the arrival and departure times separately to process events in chronological order.
Hint 2
Use a min-heap to efficiently track the earliest ending platform and determine if a new platform is needed.
Hint 3
Prove that the greedy approach of always assigning the earliest available platform yields the minimum total platforms required.
