Then, A must cross next, since we assume we should choose the fastest to make the solo-cross. Then we are at the second, or middle, pair-crossing so C and D must go. Then we choose to send the fastest back, which is B. A and B are now on the start side and must cross for the last pair-crossing. This gives us, B+A+D+B+B = 2+1+8+2+2 = 15.
Another way to see the two different questions is to simplify the Sleeping Beauty problem as follows. [10] Imagine tossing a coin, if the coin comes up heads, a green ball is placed into a box; if, instead, the coin comes up tails, two red balls are placed into a box.
In computer science, syntactic sugar is syntax within a programming language that is designed to make things easier to read or to express. It makes the language "sweeter" for human use: things can be expressed more clearly, more concisely, or in an alternative style that some may prefer.
Declarative programming may greatly simplify writing parallel programs. [ 5 ] Common declarative languages include those of database query languages (e.g., SQL , XQuery ), regular expressions , logic programming (e.g. Prolog , Datalog , answer set programming ), functional programming , configuration management , and algebraic modeling systems.
Introduced in Python 2.2 as an optional feature and finalized in version 2.3, generators are Python's mechanism for lazy evaluation of a function that would otherwise return a space-prohibitive or computationally intensive list. This is an example to lazily generate the prime numbers:

This is such good information! I wish I would've known it when we brought our puppy home. She wasn't a big biter, but looking back, I can see that she did do it when she was bored or tired.
Many developers have attempted to write programs with this core functionality, [10] however this has been met by varied results. Algorithmic skeleton frameworks are used in parallel programming to abstractly describe the methods in question for later development. The frameworks are not limited to a single type, and each of these types have ...
