Write a program to sort a dictionary's keys using Bubble sort and produce the sorted keys as a list.

Solution
my_dict = eval(input("Enter the dictionary: "))
keys = list(my_dict.keys())
l = len(keys)
for i in range(l):
    for j in range(0, l - i - 1):
        if keys[j] > keys[j + 1]:
            keys[j], keys[j + 1] = keys[j + 1], keys[j]
print("Sorted keys:",keys)
Output
Enter the dictionary: {'c':10, 'f':87, 'r':23, 'a':5}
Sorted keys: ['a', 'c', 'f', 'r']
