What is monkey patching?
...
No, it's not like any of those things. It's simply the dynamic replacement of attributes at runtime.

Immutability of Strings in Java
...

Do NOT use Activity#onRetainNonConfigurationInstance() either. This is less modular and not well-suited for Fragment-based applications.
You can read my article describing how to handle configuration changes using retained Fragments. It sol...

I'm designing an algorithm to do the following: Given array A[1... n] , for every i < j , find all inversion pairs such that A[i] > A[j] . I'm using merge sort and copying array A to array B and then comparing the two arrays, but I'm having a difficult time seeing how I can use this to find...
