CPTTRN3 - Character Patterns (Act 3)
Using two characters: . (dot) and * (asterisk) print a grid-like pattern.
Input
You are given t - the number of test cases and for each of the test cases two positive integers: l - the number of lines and c - the number of columns in the grid. Each square of the grid is of the same size and filled with 4 dots (see the example below).
Output
For each of the test cases output the requested pattern (please have a look at the example). Use one line break in between successive patterns.
Example
Input: 3 3 1 4 4 2 5 Output: **** *..* *..* **** *..* *..* **** *..* *..* **** ************* *..*..*..*..* *..*..*..*..* ************* *..*..*..*..* *..*..*..*..* ************* *..*..*..*..* *..*..*..*..* ************* *..*..*..*..* *..*..*..*..* ************* **************** *..*..*..*..*..* *..*..*..*..*..* **************** *..*..*..*..*..* *..*..*..*..*..* ****************

That was a great one! Solved it in nearly 10 mins. I am getting confidence now!!! I solved it using the trick of pattern 2 and little modification. |

At first, I thought I got an idea(which is a very complex one), and suddenly I applied that, do you know what happens? Poooooof... I simply tried for 6 - 7 hours but every time I was wrong. After some time I take a deep look into the patterns then I realise that I have to modify just a few steps. Now with in 10 mins I finished this program... Experience.! Take a deep look inside the program before proceeding.

It was tricky, but when I understood the trick the program was very brief.

guys, i did it by adding 4 loops each displaying one row of the pattern. Is that the solution or was i (kind of) cheating? lemme know |

Code output for example input matches exactly on Ideone.com, but gives "wrong answer" when submitted. Not sure what the issue is. |

It is quite easy if you observe the positions of asterisk columns mod 3. The procedure for placing rows is the same thing. |
