Question
In a classroom, each student is assigned a unique identification number representing their academic performance. Develop a program that takes the student IDs as input and implements a bubble sort algorithm to sort the IDs based on the sum of the digits in ascending order. Input the number of students and their IDs, and then display the sorted list in ascending order of the sum of digits.Input format :The first line of input consists of an integer N, representing the number of students.The second line consists of N space-separated integers, representing the unique identification numbers assigned to each student.Output format :The output prints the sorted list of student IDs based on the sum of their digits.If two or more students have the same sum of digits, maintain their original input order.
Solution
Sure, here is a Python program that implements the bubble sort algorithm to sort the student IDs based on the sum of the digits in ascending order.
def sum_of_digits(num):
return sum(int(digit) for digit in str(num))
def bubble_sort(arr):
n = len(arr)
for i in range(n):
for j in range(0, n-i-1):
if sum_of_digits(arr[j]) > sum_of_digits(arr[j+1]):
arr[j], arr[j+1] = arr[j+1], arr[j]
return arr
n = int(input("Enter the number of students: "))
ids = list(map(int, input("Enter the student IDs: ").split()))
sorted_ids = bubble_sort(ids)
print("Sorted IDs: ", sorted_ids)
Here's how the program works:
- The
sum_of_digitsfunction calculates the sum of the digits of a number. - The
bubble_sortfunction sorts the array of student IDs in ascending order based on the sum of their digits. If two IDs have the same sum of digits, their original order is maintained. - The user is asked to input the number of students and their IDs.
- The IDs are sorted using the
bubble_sortfunction and the sorted list is printed.

Problem StatementIn a computer science class, students are assigned unique identification letters based on their seating arrangement. Each student has a specific letter, and you are tasked with creating a program to sort these letters in ascending order using the bubble sort algorithm. The sorting should be based on their ASCII values. Input the total number of students and their assigned letters, then display the sorted list, allowing the students to easily identify their seating order.Input format :The first line of input consists of an integer N, representing the total number of students.The second line consists of N space-separated characters, each representing the unique identification letter assigned to a student.Output format :The output prints the sorted list of identification letters based on their ASCII values.Refer to the sample output for formatting specifications.Code constraints :1 ≤ N ≤ 15Each identification letter is a valid ASCII character.The input characters are case-sensitive.Sample test cases :Input 1 :5a y h j oOutput 1 :a h j o y Input 2 :7Q G Y O M N BOutput 2 :B G M N O Q Y Input 3 :8a e T V z X h KOutput 3 :K T V X a e h z
