Java Reference
In-Depth Information
write a recursive program that outputs all combinations of each subarray in order.
In the previous example, the desired output (although it does not have to be in
this order) is
A 1 XX
A 1 YY
A 1 ZZ
A 2 XX
A 2 YY
A 2 ZZ
B 1 XX
B 1 YY
B 1 ZZ
B 2 XX
B 2 YY
B 2 ZZ
Your program should work with arbitrarily sized arrays in either dimension. For
example, the following data
String[][] data = {
{"A"},
{"1"},
{"2"},
{"XX","YY"}
};
should output:
A 1 2 YY
A 1 2 YY
