Mutable and Immutable

• Read the guideline before start
• Implement the task:

There are 8 variables of different data types in the main module.

Your task is to create dictionary sorted_variables with two keys: "mutable" and "immutable". Each value should be equal to a list that contains all variables of corresponding type.

Example with other variables:

a = 123
b = []
c = "Hi!"
d = [1, 2]

sorted_variables = {
    "mutable": [b, d],
    "immutable": [a, c]
}
