How can I get the perfect numbers in arduino one?

hi again, i have another practice I can't solve about generating the perfect numbers serie??

When is the assignment due to be handed in? What level of notes do you need added to the code? Is GOOGLE broken in your internet?

void setup() {
 
 Serial.begin(115200);
 
   int coef = 1, space, i, j;
   int rows = 10;
 
   for (i = 0; i < rows; i++) {
      for (space = 1; space <= rows - i; space++)
         Serial.print(" ");
 
      for (j = 0; j <= i; j++) {
         if (j == 0 || i == 0)
            coef = 1;
         else
            coef = coef * (i - j + 1) / j;
         Serial.print(coef);
         Serial.print(" ");
      }
 
      Serial.println();
   }
}

void loop() {


}

Best of luck getting an A+ grade.

Ignoring the Arduino or coding for now, can you write on a piece of paper instructions to create the output you want?

For instance
myvarialbe = 1

  1. print"1"
  2. print "11"
  3. add 1 to myvariable
  4. Print "1"
  5. Print myvariable, myvariable times.
  6. Print "1"
  7. add 1 to myvariable
  8. repeat 4 - 7
  9. now define when to stop.

Nice toy. I'd ended up grabbing a Wemos D1 to test my scruffy code.
