PAT 甲级 1083 List Grades

https://pintia.cn/problem-sets/994805342720868352/problems/994805383929905152

Given a list of N student records with name, ID and grade. You are supposed to sort the records with respect to the grade in non-increasing order, and output those student records of which the grades are in a given interval.

Input Specification:

Each input file contains one test case. Each case is given in the following format:

N
name[1] ID[1] grade[1]
name[2] ID[2] grade[2]
... ...
name[N] ID[N] grade[N]
grade1 grade2

where name[i] and ID[i] are strings of no more than 10 characters with no space, grade[i] is an integer in [0, 100], grade1 and grade2 are the boundaries of the grade's interval. It is guaranteed that all the grades are distinct.

Output Specification:

For each test case you should output the student records of which the grades are in the given interval [grade1, grade2] and are in non-increasing order. Each student record occupies a line with the student's name and ID, separated by one space. If there is no student's grade in that interval, output NONE instead.

Sample Input 1:

4
Tom CS000001 59
Joe Math990112 89
Mike CS991301 100
Mary EE990830 95
60 100

Sample Output 1:

Mike CS991301
Mary EE990830
Joe Math990112

Sample Input 2:

2
Jean AA980920 60
Ann CS01 80
90 95

Sample Output 2:

NONE

 

代码：

#include <bits/stdc++.h>
using namespace std;

const int maxn = 1e5 + 10;
int N;
int L, R;

struct Node{
    char name[15];
    char id[15];
    int score;
}node[maxn];

bool cmp(const Node& a, const Node& b) {
    return a.score > b.score;
}

int main() {
    scanf("%d", &N);
    for(int i = 0; i < N; i ++)
        scanf("%s%s%d", node[i].name, node[i].id, &node[i].score);
    scanf("%d%d", &L, &R);
    sort(node, node + N, cmp);
    int cnt = 0;
    for(int i = 0; i < N; i ++) {
        if(node[i].score >= L && node[i].score <= R) {
            cnt ++;
            printf("%s %s
", node[i].name, node[i].id);
        }
    }
    if(!cnt) printf("NONE
");
    return 0;
}
