Question
In python
Write and test a function called decimal_to_binary() that takes a positive integer as the
parameter and returns a string representing that number in binary. Your program should
not use the built-in bin() function for the conversion. You may use it to test your function
to verify the answers of your function.
The algorithm for decimal to binary conversion is as follows:
1. Let num be the input and let output be an empty string ("")
2. Let p be the largest number that is a power of 2 less than or
equal to num
3. Repeat until p is 0:
3.1
If pnum, then subtract p from num and add a "1" to
the output
3.2
3.3
k
Otherwise, add a "0" to the output
Divide p by 2 and keep the integer part (floor division)
4. Return output
Note: you need to use your pow_of_two() function in step 2 of this algorithm.
Sample outputs:
decimal_to_binary (1) "1"
decimal_to_binary (3) "11"
decimal_to_binary (4) "100"
decimal_to_binary (15) "1111"
