Question

Three Patterns Given two numbers N and K, output three squares with the size N × N each with their own set of rules:

• The first square is made entirely using the ‘#’ symbol.

• The second square is made using the ‘.’ symbol except for every K rows use the ‘#’ symbol instead. • The third square is made using the ‘.’ symbol except for every K columns use the ‘#’ symbol instead.

Also print new line (\n) after printing each square. Look at sample input/output for more clarity.

Format Input The input consists of one line containing two numbers N and K.

Format Output The output consists of three squares with the size N × N according to the rules stated above. Don’t forget to print new line after printing each square!

Constraints

Answer 1

Below is the complete C code. If you face any difficulty while understanding the code, Please let me know in the comments.

Code:

#include <stdio.h>

int main() {
// declare variables and take input of N and K
long long int N,K;
scanf("%lld %lld", &N, &K);
  
// declare and initialize two variables to traverse the loop
long long int i = 1, j = 1;
  
// Print first square
for(i = 1 ; i <= N ; i++) {
for(j = 1 ; j <= N ; j++)
printf("#");
printf("\n");
}
  
printf("\n");
  
// Print second square
for(i = 1 ; i <= N ; i++) {
for(j = 1 ; j <= N ; j++)
if(i % K == 0)
printf("#");
else
printf(".");
printf("\n");
}
  
printf("\n");
  
// Print Third square
for(i = 1 ; i <= N ; i++) {
for(j = 1 ; j <= N ; j++)
if(j % K == 0)
printf("#");
else
printf(".");
printf("\n");
}
  
return 0;
}
