Day 56: Pattern using loops of 100DaysCodingChallenge

Hello all, 

#day56 

Day56 

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

Hollow Half Pyramid Numbers Pattern

1
1 2
1 3
1 4
1 5

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(k === 1 || k === i || i === n) {
      string += k+" ";
    }
    else {
      string += " ";
    }
  }
  string += "\n";
}
console.log(string);
  
  
}
hollow(n);

Output :     

 

Happy Coding:)
