幻方是一种古老的、流行的数学游戏,由于幻方不涉及到高深的数学知识且趣味性强,因此,人们对幻方的兴趣至今未衰.将9个不同的数填入3×3(三行三列)的方格表(方格盘)中,如果每个横行、每个竖列以及两条斜对角线上的3个数之和都相等(记此和为k),那么这样的图表称为三阶幻方,并称k Magic square is an ancient and popular mathematical game. Because the magic square does not involve advanced mathematics knowledge and is very interesting, people’s interest in the magic square is still alive. Fill 9 different numbers into 3× In the 3 (three rows and three columns) checkerboard (checkerboard), the sum of the three numbers on each horizontal row, each vertical row, and two diagonal diagonals is equal (note this and k). , then such a chart is called a third-order magic square and is called k
