CPTTRN1 - Character Patterns (Act 1)

Using two characters: . (dot) and * (asterisk) print a chessboard-like pattern. The first character printed should be * (asterisk).


You are given t < 100 - 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 pattern (l, c < 100).


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.

@Mitch Schwartz - thank you. Missing newline appended.

The last line of input isn't terminated with a newline in at least one input file.

Edit: Thanks!
