Write a program to sort the (name, age, height) tuples by ascending order where name is string, age and height are numbers. The tuples are input by the user. The sort criteria is:
1: Sort based on name;
2: Then sort based on age;
3: Then sort by score.
The priority is that name >age >score.
If the following tuples are given as input to the
program:
ram,19,20
Shyam,15,67
Raju,13,90
Rakesh,17,78
Then, the output of the program should be:
[('Raju', '13', '90'), ('Rakesh', '17', '78'), ('Shyam', '15', '67'), ('ram', '19', '20')]

Write a program to create list of the random number and show the normal code and efficient code for buble sort. The program should implement through
functions.
