Maximum Difference in Array – C++
Lets assume we have a sorted array like : What is the maximum difference for two elements in this array such that larger member should appear after smaller one ? If it is sorted, we can simply say that maximum difference is between last element and first element. Simply 9-1 […]
What is Singleton Pattern in C++ ?
If you need an object which should present as one instance, then a singleton pattern can be the answer for you. But If you quickly search the internet, you can see some people say that the singleton pattern is an antipattern. I am not sure it is correct 100 percent, […]
Understand loss function with Gradient Descent method using simple Python script
It is all about to distance to the local min/max point. Gradient descent is used mainly in AI applicaitons. I will not bother you to explain the details of it. But I will give you an answer for the question that I asked myself before. The question is that how […]

Arduino Voltmeter
To measure the voltage, you need an ADC. Which is called Analog to Digital converter. In arduino, for instance uno has 10 bit ADC, that means you can measure whatever you want as a 10 bit resolution that also means your scale is between 0 to pow(2,10). If you have […]
