Java generics type erasure: when and what happens?
...cks and execution-time casts. So this code:
List<String> list = new ArrayList<String>();
list.add("Hi");
String x = list.get(0);
is compiled into
List list = new ArrayList();

In these scenarios what is the impact of multiple (perhaps nested) try catch blocks within the tight loop. Some optimizations will be skipped by the compiler ...

If an odd number of backslashes is followed by a double quotation mark, then one backslash () is placed in the a...
Throwing cats out of windows
...sily find strategy (how to throw first cat), if you save best k in another array.
There's also a faster solution, not involving O(n^3) computations, but I'm a bit sleepy already.
