언어 : Kotlin

 

문제 설명 :

Little hobbitses go to hobbit school in the Shire. They just finished a course, which involved tea-making, meal-eating, nap-taking, and gardening. Based on the following grading scale, assign each hobbit a letter grade based on their final numerical course grade.

 

• A+: 97-100
• A: 90-96
• B+: 87-89
• B: 80-86
• C+: 77-79
• C: 70-76
• D+: 67-69
• D: 60-66
• F: 0-59

 

입력 :

The input will begin with a single line containing just a whole number, n, of the number of hobbits in the class, followed by n lines in the form a b, where a is the hobbit’s name (only alphabetical characters) and b is the hobbit’s grade, given as a whole number. The length of hobbit's name is less than 10.

 

출력 :

For each test case, print out a list of every hobbits name and letter grade, each on its own line. There should be no additional white space following test cases.
