Might that post is deleted now

Answer 2

● 1 loop for rows
● inside it 2 loops : 1 for spaces & 1 for stars
//Michal gave a nice understadable code for it
● Just some tip by which U can remove 1 inner loop for stars : stars are following pattern 1, 2, 3, 4 , ... //that is an A.P.
So U can do something like :
String star ="";
//and in every iteration of outer loop print(star += "*");
OR
String star = "*";
//and in every iteration of outer loop, the last 2 statement to be executed should be
System.our.println(star);
star = star +"*";

There are much more approaches to it, might more efficient ones are also there, U can post a code next time with doubt to get better help 👍

Answer 4

Michal
now the general approach is only mentioned in my comment.
//I always do this only, whenever I find some increasing A.P. is there ☺

Gaurav Agrawal The same question was asked at 13.01.
In the comments of my code you find the old link. Maybe you should know this.

Answer 8

Gaurav Agrawal It was on 9.1. not on 13.1.
And if you look at Zulfitri's posts you find another version of this question from 8.1.
Could it be a bot?

Answer 9

Sorry. I need the code for my exam
