Question

Write a program whose input is two integers. Output the first integer and subsequent increments of 5 as long as the value is less than or equal to the second integer. Ex: If the input is: - 15 10 the output is: -15 -10 -5 0 5 10 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last. 5.17 LAB: Print string in reverse Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters "Done", "done", or "d" for the line of text. Ex: If the input is: Hello there Hey done then the output is: ereht olleh уен 275344.1613222

Answer 1

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.
