( 38241 ) B Upscaling PROGRAMMING implementation

B"You are given an integer n . Output a 2n x 2n checkerboard made of 2 x 2 squares alternating ' texttt{#} ' and ' texttt{.} ', with the top-left cell being ' texttt{#} '. The picture above shows the answers for n=1,2,3,4 . The first line contains an integer t ( 1 <= q t <= q 20 ) -- the number of test cases. The only line of each test case contains a single integer n ( 1 <= q n <= q 20 ) -- it means you need to output a checkerboard of side length 2n . For each test case, output 2n lines, each containing 2n characters without spaces -- the checkerboard, as described in the statement. Do not output empty lines between test cases. "...
