Hello all,

Day46 

Today's my task was to Print the below Pattern using loops.

Hollow Full Pyramid Star Pattern

      *
    *   *
   *     *
  *       *
 ***********

I have started the 100 days of coding challenge to improve my programming skills..

Code : 

let n = prompt("Enter a  number : ");
let string  = "";
function hollow(n) {
  //let n = 5;
let string = "";

// External loop
for (let i = 1; i <= n; i++) {
  // printing spaces
  for (let j = 1; j <= n - i; j++) {
    string += " ";
  }
  // printing star
  for (let k = 1; k <= 2 * i - 1; k++) {
    if(i === 1 || i === n) {
      string += "*";
    }
    else {
      if(i == n || k==1 || k==(2 * i - 1)) {
        string += "*";
      }
      else {
        string += " ";
      }
    }
  }
  string += "\n";
}
console.log(string);
  
  
}
hollow(n);

Output :     

 

Happy Coding:)
