A+B Problem

A+B problem is a challenge that reads two decimal integers, add, and output.

Usually, the input value is constrained in some way.

For languages that can't do I/O, the "input" is done by manually modifying the program before it is executed so that it stores its two numbers in the memory, the "output" is done by storing the result in the memory.

The following is a not so decent implementation in brainfuck, by User:None1.

,------------------------------------------------>,,------------------------------------------------[-<+>]<++++++++++++++++++++++++++++++++++++++++++++++++.

Both the input and the result have to be one-digit numbers, and the two numbers in the input are separated by exactly one space (or any other character, but there must be exactly one).

Actually I have a better one that uses algorithms mentioned in brainfuck algorithms.

[-]>[-]+[[-]>[-],[+[-----------[>[-]++++++[<------>-]<--<<[->>++++++++++<<]>>[-<<+>>]<+>]]]<]>>[-]>[-]+[[-]>[-],[+[-----------[>[-]++++++[<------>-]<--<<[->>++++++++++<<]>>[-<<+>>]<+>]]]<]<[-<<<+>>>]<++++++++++<<[->+>-[>+>>]>[+[-<+>]>+>>]<<<<<<]>>[-]>>>++++++++++<[->-[>+>>]>[+[-<+>]>+>>]<<<<<]>[-]>>[>++++++[-<++++++++>]<.<<+>+>[-]]<[<[->-<]++++++[->++++++++<]>.[-]]<<++++++[-<++++++++>]<.

It only works on 8 bit cells, and the numbers in the input and the result should not exceed 255. The two numbers in the input are separated by line feeds.

class Main {
    public static void main(String[] args) {
        Scanner sc=new Scanner(System.in);
        int a=sc.nextInt();

Func++

intoutput(add(intinput(),intinput())

JavaScript

function add(a,b){
    console.log(a+b);
}

I use a function, because it seems that JavaScript has no functions for input.

Powershell

$a=read-host
$b=read-host
$c=[Convert]::ToInt32($a)+[Convert]::ToInt32($b)
write-host $c

Python

print(sum([int(i) for i in input().split()]))
