• Read student records: name, course number, and final grade
• Filter: Keep only students with course number 124
• Sort: Alphabetically by name (ascending)
• Write filtered and sorted data to output file
• Maximum capacity: 10 students

Sample Input and Output

Input file (input.txt):

studentX 124 88.5
studentY 118 66.5
studentA 123 76.2
studentD 124 90.3
studentB 123 76.2
studentF 124 70.3

Output file (output.txt):

studentD 90.3
studentF 70.3
studentX 88.5
