Integer is more efficient than int in Java?
By meijun, 10 years ago, In English

I was really confused. Look at this two submissions: 6826675 6826691.

The only difference between the two submissions is the replace of int by Integer. However, the pre is TLE with 1000 ms, and the other is AC with 358 ms.

Could you tell me why?
