Given an positive integer A (1 <= A <= 109), output the lowest bit of A. For example, given A = 26, we can write A in binary form as 11010, so the lowest bit of A is 10, so the output should be 2. Another example goes like this: given A = 88, we can write A in binary form as 1011000, so the lowest bit of A is 1000, so the output should be 8.

Writing Your First ASP Application ( Quick Start ) (Page 1 of 8 ) There are many tutorials out there that show you how to program in ASP. Some of them are good, and some are bad. Some of them are downright terrible. In any case, you ve read a bit about ASP and now you are ready to build your first application. But where do you start? In my own experience, I have found that I find it easier to learn something if I actually work with it hands-on. Just reading a book or documentation doesn’t give you the practical knowledge you need to be able to rush off and start creating applications. In this article, I will discuss the creation of a very simple application. I will cover what the application will do, how we will approach writing it, demonstrate in code how we will do it, and discuss additional features that could be added to it.

Easy-to-Use, Ultra-Tiny, Differential, 16-Bit Delta Sigma ADC With I2C Interface The LTC2453 is an ultra-tiny, fully differential, 16-bit, analog-to-digital converter. The LTC2453 uses a single 2.7V to 5.5V supply and communicates through an I2C interface. The ADC is available in an 8-pin, 3mm x 2mm DFN package. It includes an integrated oscillator that does not require any external components. It uses a delta-sigma modulator as a converter core and has no latency for multiplexed applications. The LTC2453 includes a proprietary input sampling scheme that reduces the average input sampling current several orders of magnitude lower than conventional delta-sigma converters. Additionally, due to its architecture, there is negligible current leakage between the input pins.
