A decimal, or base 10, number is a number expressed in the everyday format that we are all used to. We can also express numbers with the binary system, which expresses numbers in powers of 2. For example, 8 (base 10 number) translates to '1000' (binary number). 23 22 21 20 '1' or '0' indicates whether the value that it represents is included in the base 10 value. 8 can just be represented with 23, so we represent this with a '1' in that corresponding placement and '0' for other powers of 2. As another example, 5 would translate to '101'. 1 000 22 2¹ 20 For numbers that are not powers of 2, like 5, we represent them with several powers of 2. We use 22 and 2⁰ for 5. 101 Notice that we always start with the power of 0 at the right. Now that you know how to read binary numbers, let's try to implement binary. Write the recursive function binary which takes in n, a base 10 number, and returns a list representing the representation of the number in base 2. You may find the following article helpful in understanding how to convert a number from decimal to binary. def binary (n): """Return a list representing the representation of a number in base 2. >>> binary (-136) ['-', 1, 0, 0, 0, 1, 0, 0, 0] |||||| >>> binary (55055) [1, 1, 0, 1, 0, 1, 1, 1, 0, 0, 0, 0, 1, 1, 1, 1] latestest YOUR CODE HERE ****"

Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.
Question
![A decimal, or base 10, number is a number expressed in the everyday format that we are all used to. We
can also express numbers with the binary system, which expresses numbers in powers of 2.
For example, 8 (base 10 number) translates to '1000' (binary number).
1000
23 22 21 2⁰
'1' or '0' indicates whether the value that it represents is included in the base 10 value. 8 can just be
represented with 2³, so we represent this with a '1' in that corresponding placement and '0' for other
powers of 2.
As another example, 5 would translate to '101'.
1 0 1
22 21 20
For numbers that are not powers of 2; like 5, we represent them with several powers of 2. We use 2² and 20
for 5.
Notice that we always start with the power of 0 at the right.
Now that you know how to read binary numbers, let's try to implement binary. Write the recursive
function binary which takes in n, a base 10 number, and returns a list representing the representation of
the number in base 2.
You may find the following article helpful in understanding how to convert a number from decimal to binary.
def binary (n):
"""Return a list representing the representation of a number in base 2.
"*** YOUR CODE HERE ***"/
>>> binary (55055)
[1, 1, 0, 1, 0, 1, 1, 1, 0, 0, 0, 0, 1, 1, 1, 1]
>>> binary (−136)
