CPTTRN4 - Character Patterns (Act 4)

#basics

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 width 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:
***
*.*
*.*
***
*.*
*.*

*.*
*.*

	kkislay20: 2017-12-26 12:57:35 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 .

	levim: 2015-10-27 18:19:47 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.
