Test Case

Run npm test to run the test case.

The test will check if both solve24game() and ordinary method have or don't have answer, for each pairs of 4 numbers between 1 and 13, goals within 1 and 99.

After the test finished successfully, it will output how many pairs of 4 numbers out of 1820 pairs have answer for each goals.

The test will take about 12 minutes to finish.
