Hello World
Welcome Welcome! HelloWorld This is a simple test for my first blog article. Mathjax Test 1 $$a_{PI}(x|D) = E[u(x) | x, D] = \int_{-\infty}^{f’} \mathcal{N}(f; \mu(x), \kappa(x, x)) \ df =\phi(f’; \mu(x), \kappa(x, x))$$ Test 2 $$\frac{e}{\left( e+e^{\pi} - \pi^{e}\right) ,\left( - e+\pi^{e}\right) }+{E(\left( e+\pi\right) ,\left( 2,e+\pi\right) )}^{e}$$ C #include <stdio.h> int main() { printf("HelloWorld!\n"); return 0; } C++ #include <iostream> int main() { std::cout << "HelloWorld!" << std::endl; return 0; } Java public class Main { public static void main(String[] args) { System.out.println("HelloWorld!"); } } Python print("HelloWorld!")
