1083. List Grades (25)
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

for(i=0;i<n;i++)
{
scanf("%s %s %d",name,id,&m);
strcpy(stud[m].name,name);
strcpy(stud[m].id,id);
stud[m].tag=-1;
}
scanf("%d %d",&k,&t);
flag=0;
for(i=t;i>=k;i--)
{
if(stud[i].tag==-1)
{
printf("%s %s\n",stud[i].name,stud[i].id);
flag=1;
}
}
if(flag==0)
{
printf("NONE\n");
}
return 0;
