我主要是不知道如何选择不同的数做题目
1. 以不同的字母代表0-9之间的数字,现有如下等式成立:a+bc+def=ghij 编程求出满足上述条件等式的个数并将所有等式打印输出.
2.将5,6,7,8,9填入(口口口*口口)的空格中,使他们的积有最大值!
3.已知四个小朋友:甲,乙,丙,丁,体重都是整数公斤,且甲<乙<丙<丁,又四人中任何两人体重和如下:35,39,44,45,50,54,请计算一下甲乙丙丁的体重各各自究竟是多少?
4.在2,3,5,7,9这五个数中选取四个数组成被3和5除都余2的四位数,这样四位数有什么?

第一题答案：
s=0
g = 1
h = 0
d = 9
FOR a = 2 TO 8
FOR b = 2 TO 8
FOR c = 2 TO 8
FOR e = 2 TO 8
FOR f = 2 TO 8
FOR i = 2 TO 8
FOR j = 2 TO 8
IF (a + b + c + d + e + f + g + h + i + j = 45) AND (a * b * c * d * e * f * g * i * j = 362880) AND (a + b * 10 + c + d * 100 + e * 10 + f = g * 1000 + h * 100 + i * 10 + j) THEN
PRINT a; "+"; b * 10 + c; "+"; d * 100 + e * 10 + f; "="; g; h; i; j
s = s + 1
END IF
NEXT
NEXT
NEXT

NEXT
PRINT s
END
打印格式你调整一下就可以了
