Write a program whose input is two integers. Output the first integer and subsequent increments of 5 as long as the value is les
adell [148]

Answer:

Following are the code to the given question:

For code 1:

start = int(input())#defining a start variable that takes input from the user end

end = int(input())#defining a end variable that takes input from the user end

if start > end:#use if that checks start value greater than end value

   print("Second integer can't be less than the first.")#print message

else:#defining else block

   while start <= end:#defining a while loop that checks start value less than equal to end value

       print(start, end=' ')#print input value

       start += 5#incrementing the start value by 5

   print()#use print for space

For code 2:

while True:#defining a while loop that runs when its true

   data = input()#defining a data variable that inputs values

   if data == 'Done' or data == 'done' or data == 'd':#defining if block that checks data value

       break#use break keyword

   rev = ''#defining a string variable rev

   for ch in data:#defining a for loop that adds value in string variable  

       rev = ch + rev#adding value in rev variable

   print(rev)#print rev value

Explanation:

In the first code two-variable "first and end" is declared that takes input from the user end. After inputting the value if a block is used that checks start value greater than end value and use the print method that prints message.

In the else block a while loop is declared that checks start value less than equal to end value and inside the loop it prints input value and increments the start value by 5.

In the second code, a while loop runs when it's true and defines a data variable that inputs values. In the if block is used that checks data value and use break keyword.

In the next step, "rev" as a string variable is declared that uses the for loop that adds value in its variable and prints its values.

What are the pros and cons of MP3 audio archives?
UkoKoshka [18]
Was this in reference to literal audio archives? If so, I don't see any cons beside possible copyright infringement.

If you're talking about the codecs themselves, then I can do that.

<span>Pros:

</span>- Widespread acceptance. Supported in nearly all hardware devices, and continually adopted by newer ones.

- Faster decoding. Much more so than FLAC, Vorbis, etc.

- Relaxed licensing schedule.

<span>Cons:
</span><span>
</span>- Lower quality and efficiency than most modern codecs. (To be fair, never really noticed this one).

- Sometimes the maximum bitrate isn't enough.

- Pretty much void/unusable for high definition audio (higher than <span>48kHz).</span>
