Code:

def histogram(l):
count_dict = {}
for num in l:
if num in count_dict:
count_dict[num] += 1
else:
count_dict[num] = 1

sorted_count = sorted(count_dict.items(), key=lambda x: (x[1], x[0]))
return sorted_count

def transcript(coursedetails, studentdetails, grades):
Convert course details to dictionary for faster lookup
course_dict = {course[0]: course[1] for course in coursedetails}

Create a dictionary to hold student grades
student_grades = {}
for grade in grades:
rollno, course, g = grade
if rollno in student_grades:
student_grades[rollno].append((course, course_dict[course], g))
else:
student_grades[rollno] = [(course, course_dict[course], g)]

Sort each student's grades
for rollno, grade_list in student_grades.items():
student_grades[rollno] = sorted(grade_list, key=lambda x: x[0])

Create final list
final_list = []
for student in studentdetails:
rollno, name = student
final_list.append((rollno, name, student_grades.get(rollno, [])))

Sort the final list by roll number
return sorted(final_list, key=lambda x: x[0])
