Answer:
The Python code with the function is given below. Testing and output gives the results of certain chosen parameters for the program
Explanation:
def first_last(seq):
if(len(seq) == 0):
return ()
elif(len(seq) == 1):
return (seq[0],)
else:
return (seq[0], seq[len(seq)-1])
#Testing
print(first_last([]))
print(first_last([1]))
print(first_last([1,2,3,4,5]))
# Output
( )
( 1 , )
( 1 , 5 )

Answer:
video codecs
Explanation:
A video converter can be defined as a software application or program designed to avail end users the ability to convert video files from one digital format to another. After the conversion of the video is complete, the components of the video format such as aspect ratio (e.g 16:9, 4:3 etc), resolution (e.g 1028×760, 640×320), audio and video codecs (e.g mp3, mp4, H.264 etc), the bit rate are also converted depending on the choice of the user.
Encoding a video format and then decoding it during playback is one of the functions of MPEG-4 and H.264 file players. MPEG-4 and H.264 are known as video codecs.
Answer:
dependent variable -- As it depends on the other variables, changes when they change
Answer:
See below
Explanation:
Because sometimes you have to 'carry' a 1 over to the ext column when adding two binary numbers
Example :
1 1 1
<u>+1 1 1 </u> <==== starting in the first R column add 1 + 1 to get 0 and carry 1
then the next column you will add 1 + 1 + 1 = 1 and carry 1 again
then 1 + 1 + 1= 1 and carry 1 again (to column 4) to get
1 1 1 0
