Student Grades Sorting

You are provided a list of student names and their grades in the format 'Name,Grade'. Your task is to sort the students first by their grades in ascending order, and in the case of ties, by their names in alphabetical order. Print the sorted list in the same 'Name,Grade' format. Input format: - The first line contains an integer n (1 ≤ n ≤ 1000), the number of students. - The following n lines each contain a student's record. Output format: - Print the sorted student records, one per line. Example: Input: 3 Alice,85 Bob,70 Charlie,85 Output: Bob,70 Alice,85 Charlie,85
