There are two test files for writing the code:
- t1.txt contains 5,000 items;
- t2.txt contains 10,000 items;
All 7-digit numbers in each file are distinct, but they may duplicate in two files.
Of course, you can generate more items if you want, please look at the
index.jsfile under directoryNonRepeatedRadomNumGenerator. If you want to generate more test files,node.jsenvironment is required.
