5.19 LAB: Countdown until matching digits Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical. Ex: If the input is:

Following are the code to this question:

x = int(input())#defining a variable x for user input value  

if(x>=20 and x<=98):#defining an if block that checks value is in between 20 to 98  

   while(not(x%10==x//10)):#defining while loop that seprate numbers and checks it is not equal  

       print(x)#print value

       x-=1# decrease value by subtracting 1

   print(x)# print value

else:#defining else block  

   print("The input value must lie in 20-98")#print message

Output:

Explanation:

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
