2460번: 지능형 기차 2

 내 풀이 

#include<iostream>

using namespace std;

int exit_people = 0;
int enter_people = 0;

int cnt_people;
int max_people = 0;

int main()
{
	for (int i = 0; i < 10; i++)
	{
		cin >> exit_people >> enter_people;
		cnt_people += enter_people - exit_people;
		if (max_people <= cnt_people) max_people = cnt_people;
	}

	cout << max_people;
}

 해설

역마다 타는 사람에 내리는 사람 수를 빼주고 최고값을 비교해주었다.
