Question1: Student Grades Processing
You need to write a Python program to process a student's grades. The program needs to perform the following functions:

Store information and notes for 10 students using a dictionary. Let each student have their name, surname and grades (Midterm, Final and Oral grades). For example:

students = {
"Ahmet Yılmaz": [85, 90, 78], #Midterm: 85, Final: 90, Oral: 78
'Mehmet Demir': [92, 88, 76], #Midterm: 92, Final: 88, Oral: 76
"Ayşe Kaya": [78, 89, 95], #Midterm: 78, Final: 89, Oral: 95
"Zeynep Çelik": [65, 70, 80], #Midterm: 65, Final: 70, Oral: 80
'Ali Kara': [50, 60, 55], #Midterm: 50, Final: 60, Oral: 55
'Fatma Yıldız': [88, 85, 90], #Midterm: 88, Final: 85, Oral.: 90
'Murat Aydın': [72, 68, 74], #Midterm: 72, Final: 68, Oral: 74
'Elif Aksoy': [95, 98, 88], #Midterm: 95, Final: 90, Oral: 88
"Hakan Öztürk": [45, 50, 55], #Midterm: 45, Final: 50, Oral: 55
"Canan Taş": [80, 75, 82] #Midterm: 80, Final: 75, Oral: 82
}

1-Calculate each student's GPA and add it to the dictionary.

2-Find the student with the highest GPA and print it on the screen.

3- Separate each student's name from their surname and store them in a separate tuple and add them to a list.

4-Sort the names in alphabetical order and print the sorted list on the screen.

5-Keep students with a GPA below 70 in a cluster (set).
