CPTTRN4 - Character Patterns (Act 4)


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 four positive integers: l - the number of lines, c - the number of columns in the grid; h and w - the high and the with of the single rectangle.

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 2 1
4 4 1 2
2 5 2 2

Output:
***
*.*
*.*
***
*.*

This is the general case for making grids...good question...had fun...AC in one go
Hint: first try to find the formula for grid then see where you have to put * and put condition for that otherwise it will print .

My code works perfectly fine with the above give test cases. But I keep getting wrong answer when I submit it.

Edit: 18-04-16: Never mind I found my mistake. Nice problem admin!

Great excercise for a novice programmer like me.I kept getting TLE so i optimized it as much as i could to then found out i was submitting it as python 3.4(3.4) instead of python 3(3.4). Atleast i learned alot about TLE this way.
