Hamcrest compare collections

...s with Hamcrest: assertEquals(expectedList, actual.getList()); If you really intend to perform an order-insensitive comparison, you can call the containsInAnyOrder varargs method and provide values directly: assertThat(actual.getList(), containsInAnyOrder("item1", "item2")); (Assuming that you...

Deleting elements from std::set while iterating

... is implementation dependent: Standard 23.1.2.8: The insert members shall not affect the validity of iterators and references to the container, and the erase members shall invalidate only iterators and references to the erased elements. Maybe you could try this -- this is standard conforming:...

C# vs Java generics [duplicate]

...ges. A few quirks here and there (most notably in constraints). But basically if you can read one, you can likely read/use the other. The biggest difference though is in the implementation. Java uses the notion of type erasure to implement generics. In short the underlying compiled classes ...

Computational complexity of Fibonacci Sequence

...ll have depth n and intuitively figure out that this function is asymptotically O(2n). You can then prove your conjecture by induction. Base: n = 1 is obvious Assume T(n-1) = O(2n-1), therefore T(n) = T(n-1) + T(n-2) + O(1) which is equal to T(n) = O(2n-1) + O(2n-2) + O(1) = O(2n) However, as ...
