各种情况的解个数,23 7是最多的,注意转置矩阵副对角线会反,要判断是否还为质数(11 1) num = 3 (11 3) num = 1 (11 5) num = 1 (13 1) num = 3 (13 2) num = 6 (13 3) num = 9 (13 4) num = 1 (17 1) num = 41 (17 2) num = 49 (17 3) num = 58 (17 4) num = 21 (17 5) num = 11 (17 6) num = 5 (17 7) num = 3 (19 1) num = 45 (19 2) num = 32 (19 3) num = 57 (19 4) num = 30 (19 5) num = 43 (19 6) num = 23 (19 7) num = 13 (19 8) num = 6 (19 9) num = 14 (23 1) num = 64 (23 2) num = 96 (23 3) num = 120 (23 4) num = 53 (23 5) num = 78 (23 6) num = 89 (23 7) num = 125 (23 8) num = 42 (23 9) num = 30 (25 1) num = 59 (25 2) num = 83 (25 3) num = 64 (25 4) num = 71 (25 5) num = 86 (25 6) num = 47 (25 7) num = 58 (25 8) num = 38 (25 9) num = 33 (29 1) num = 16 (29 2) num = 17 (29 3) num = 21 (29 4) num = 16 (29 5) num = 46 (29 6) num = 44 (29 7) num = 22 (29 8) num = 36 (29 9) num = 24 (31 4) num = 3 (31 5) num = 12 (31 6) num = 4 (31 7) num = 4 (31 8) num = 2 (31 9) num = 7 (35 3) num = 1 (35 5) num = 1 (35 7) num = 2 (35 9) num = 1 (37 7) num = 3 (37 9) num = 3 Followed by: Post your reply here: |
