Can someone tell me why my code failed in first case and passes in second case

During the contest I used Array of Integer type to avoid TLE, which can occur with array of primitive ints but that led to wrong answer but after I tried with array of primitives and I got AC. Can someone tell me why this is happening?

You are checking Integer objects for equality using !=, which is comparing the underlying references. This will usually work as desired for numbers in [-128..127] because these values are singletonized, but will rarely work as desired for any other numbers.
