Codeforces Round #502 Div. 1 + Div. 2 A. The Rank

http://codeforces.com/contest/1017/problem/A

题意：每个人有4门学科，给出n个人的分数，小明的分数是第一个给出的，问小明的总分排名第几

思路：水题，求和排序即可。

#include<cstdio>
#include<iostream>
#include<string>
#include<cstring>
#include<cmath>
#include<algorithm>
using namespace std;
 
int main() 
{
	int n, a, b, c, d, sum, p, ct = 0;
	int i;
	scanf("%d", &n);
	scanf("%d%d%d%d", &a, &b, &c, &d);
	p = a + b + c + d;
	for (i = 2; i <= n; i++) 
	{
		scanf("%d%d%d%d", &a, &b, &c, &d);
		sum = a + b + c + d;
		if (sum > p) 
		{
			ct++;
		}
	}
	printf("%d\n", ct + 1);
	return 0;
