In the above code, again we are using K variable to print spaces but this time we are decrementing it by 1,i.e, k= k-1 , after each loop of printing spaces get's over, so basically logic is same as per the 2nd code, but changing it a little bit it generates equivalent triangle. This main method is using the following formula to calculate each entry of every line in Pascal's triangle: pascalEntry = pascalEntry * (line - column + 1) / column This solution is straightforward. // class Triangle .
