"""Idea:
- def a function to decode 1 byte:
    - get the list
    - get value by multiplying each element with 2** its index from reverse (pattern observation)
      .... (instead of this we can multiply index to list reversed)......
    - return the sum of value

- get input
- split it to get rid of spaces (assume user is well behaved and will enter 1-space separated string only)
- convert each byte and compile result in a list
- print the converted bytes separated by space
"""
