Countdown until matching digits Write a program that takes in an integer in the range 11-100 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical. Ex: If the input is the output is 93 92 91 90 89 88 Ex: If the input is 11 the output is 11 Ex: If the input is 9 or any number not between 11 and 100 (inclusive), the output is: Input must be 11-100 For coding simplicity, follow each output number by a space, even the last one. Use a while loop. Compare the digits do not write a large if-else for all possible same-digit numbers (11,22,33...99), as that approach would be cumbersome for larger ranges. 29999.1122120 LAB ACTIVITY 4.13.1: LAB: Countdown until matching digits 7/10 main. c Load default template... 1 include 2 3 int main() 4 int n, i: 5 scanf("%d", &n); if (n < 20 Il n98) { 7 printf("%d",n); } else { i-n: 1e while (1) printf("%d", 1); if (icie - i/10) 13 14 15 16 17 } 18 printf("\n"); 19 return : 20 ) 12 break; Latest submission - 11:16 PM on 02/05/21 Total score: 7/10 Only show failing tests Download this submission 1: Compare output A 3/3 Input Your output 93 92 91 90 89 88 2: Compare Output A Input 11 Your output 11 3: Compare output a 3/3 Input 20 Your output 20 19 18 17 16 15 14 13 12 11 4: Compare output A 0/2 Output differs.

The program in C is as follows:

#include <stdio.h>

int main(){

   int n;

   scanf("%d", &n);

   if(n<11 || n>100){

       printf("Input must be between 11 - 100");    }

   else{

       while(n%11 != 0){

           printf("%d ", n);

           n--;        }

       printf("%d ", n);    }

   return 0;

}

Explanation:

The existing template can not be used. So, I design the program from scratch.

This declares the number n, as integer

   int n;

This gets input for n

   scanf("%d", &n);

This checks if input is within range (11 - 100, inclusive)

   if(n<11 || n>100){

The following prompt is printed if the number is out of range

       printf("Input must be between 11 - 100");    }

   else{

If input is within range, the countdown is printed

       while(n%11 != 0){ This checks if the digits are identical using modulus 11

Print the digit

           printf("%d ", n);

Decrement by 1

           n--;        }

This prints the last expected output

       printf("%d ", n);    }

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
