class Solution: def reverseBits(self, n: int) -> int: # Short Version out = str(bin(n))[::-1][:-2] while len(out) < 32: out += '0' return int(out, 2) # Long, step-by-step version # First, let's see the binary of the original number #print(bin(n)) # Then, let's turn the number into binary, and a string and save it to a variable #out = str(bin(n)) #print(out) # Next, this is fancy python for: iterate through the list from end to start in increments of -1 (backwards) # returning each element. This effectively reverses the string from the step above. #out = out[::-1] #print(out) # Now, since we turned the binary representation into a string, we have a "0b" at the end (since we reversed order) # We can remove it with python indexing [:-2] #out = out[:-2] # The input binary may have had leading zeros that would have been truncated # i.e. 000101 -> 101 # When reversed, those zeros are important # 101000 =/= 101 # Since we know the input number is always 32 bits, we can just add trailing zeros until we reach a length of 32 #while len(out) < 32: # out += '0' #print(out) # Finally, we can convert back to base-10 and return! #out = int(out, 2) #return out
