Hello here is the solution to your problem in steps. \n" ); document.write( "Hope you find this helpful. \n" ); document.write( "ogunjimio79@gmail.com \n" ); document.write( "=======================\r \n" ); document.write( "\n" ); document.write( "Step 1: Understand the constraints \n" ); document.write( "- Two queens cannot share the same row, column, or diagonal. \n" ); document.write( "- A standard chessboard has 8 rows and 8 columns.\r \n" ); document.write( "\n" ); document.write( "Step 2: Calculate the total possible placements for the first queen \n" ); document.write( "- The first queen can be placed in any of the 64 squares (8 rows x 8 columns).\r \n" ); document.write( "\n" ); document.write( "Step 3: Calculate the possible placements for the second queen \n" ); document.write( "- After placing the first queen, the second queen cannot be placed in the same row, column, or diagonal. \n" ); document.write( "- This means the second queen has 36 possible squares to be placed (64 - 28 squares that are under attack by the first queen).\r \n" ); document.write( "\n" ); document.write( "Step 4: Account for overcounting \n" ); document.write( "- Since the order of placing the queens doesn't matter, we need to divide the total count by 2 to avoid counting each configuration twice.\r \n" ); document.write( "\n" ); document.write( "Step 5: Calculate the total possible ways \n" ); document.write( "- Total possible ways = (Total possible placements for the first queen) x (Possible placements for the second queen) / 2 \n" ); document.write( "- Total possible ways = 64 x 36 / 2 \n" ); document.write( "- Total possible ways = 1152\r \n" ); document.write( "\n" ); document.write( "The final answer is 1152. \n" ); document.write( "======================= \n" ); document.write( "If you're satisfied with my solution and interested in further learning , I'm available for a one-on-one online session.
