Answer 1

Here is explanation in brief, hope it will make things very clear Muralikrishnan

String str = "abcdef..k"
int l=str.length(); //we get length of String
int n=3; //0,1,2,1,0,1,2,1 & so on ..

● run the outer loop for l number of times [for a ranging from 0 to l-1]
● inside it make a loop for printing number of stars
[for b ranging from 0 to a%(3+1)]
● after inside loop over print str.charAt(a) & go to new line using "\n"

//make use of %(N+1) , correction by Louis
