Julia did white boarding test on her own code, and then she found a bug on line 29 on test case 0.001, n = 3, search value 0.1. Learn to test your own code very carefully, and then find a bug on line 29. But Julia missed the bug on line 74. The peer asked the question to point out the bug on line 75, return integerValue/ 1000.0; not integerValue/ 1.0.
