Joining of two BSTs at Page552:
Program 12.23 Joining of two BSTs
If either BST is empty, the other is the result. Otherwise, we combine the
two BSTs by (arbitrarily) choosing the root of the first as the root, root
inserting that root into the second, then (recursively) combining the pair
of left subtrees and the pair of right subtrees.
private Node joinR(Node a, Node b)

if (a == null) return b;

However, firstly I couldn’t use the known X-ray structure as template

如果你只是考虑个别情况那要从新设计，
或者直接采用回归分析的相关关系观察其相关性。
只考虑Group1-Group2，Group3-4可以用one-way ANOVA(即水平A+/A-下B的不同水平的差
异),考虑Group2-Group3,Group4-1用two-way ANOVA。
可以用SPSS分析，只需输入相关数据就行。
(或许在SPSS下直接用two-way ANOVA也可以反映所有数据，没用过不敢肯定，但是感觉结

a[0]..a[997] store the number from 1..1000,missed 2 and no duplication
The best way from Computer science is below:
###pay attention that a^a=0
int result=0;
for(int i=0;i<997;i++)
{
result = result ^ a[i];
}
for(int i=1;i<1001;i++)
{
result = result ^ i;
}
###then result is just missing number1 ^ missing number2.
since they are different,there must be one digit is not the same of the two
