搞清楚这题的意思就很容易了，该题表达的意思是要用0-9这十个数字组成5个两位数且每个数字只能使用一次，使得5个数字的和最小，问最大的两位数是多少？
要满足和最小那十位数的5个数字分别是1,2,3,4,5 那各位数就也就只剩下0,6,7,8,9这5个数了， 所以组合起来最大的就是59了

tens 十位 ten digits 10个数字（0－9） 10个数字组合成5个整数（每个数字只能用一次）整数范围[10,99] 5个整数之和最小 十位的数字只能是1－5，剩下的数字不管跟在哪个数字后总和都是一样的。最大的就是59。

叫兽700upupup
当确定十位数为1，2，3，4，5之后，它们的个位数无论是0，6，7，8，9中的哪一个（无论怎么搭配），结果都是一样的，所以最大是59

In addition, 十位数是12345，个位数怎么组合，Sum都是那个Minimum Sum. Therefore the Greatest possible integer是最大的十位数5，和最大的个位数9 搭配一起。

个位数为什么可以组合 不是要加起来最小吗 那不是10+20+30+40+50吗
