Hello all, 

#day61 

Day61 

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

Full Pyramid Triangle of Alphabets

A
B B B
C C C C C
D D D D D D D
E E E E E E E E E

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

Code : 

let a = prompt("Enter a number : ");
let string = "";
function full(a) {
  let k = 1;
  for (let i = 1; i <= a; i++) {
    //console.log('j1', a - i);
    for (let j = 2 * (a-i); j >= 0 ; j--) {
      //console.log('j1', j);
      string += " ";
    }
    //console.log('j2', i - k);
    for (let j = 2 * (i - k); j >= 0; j--) {
//console.log('j2', j);
      //string += i+" ";
      string += String.fromCharCode("A".charCodeAt(0) - 1 + i) +" ";
    }
    string += "\n";
  }
  console.log(string);
}
full(a);

Output :     

 

Happy Coding:)
