1. Hello World

console.log('Hello World!');

2. We love kriii

console.log('강한친구 대한육군\n강한친구 대한육군');

3. 고양이

console.log(`\\    /\\
 )  ( ')
 (  /  )
  \\(__)|`);

4. A+B

const fs = require('fs');
const filePath = process.platform === 'linux' ? '/dev/stdin' : './input.txt';
let input = fs.readFileSync(filePath).toString().split('\n');

input = input[0];
input = input.split(' ').map(item => Number(item));

function 답(a, b) {
    console.log(a + b);
}
답(input[0], input[1]);

5. A-B

const fs = require('fs');
const filePath = process.platform === 'linux' ? '/dev/stdin' : './input.txt';
let input = fs.readFileSync(filePath).toString().split('\n');

input = input[0];
input = input.split(' ').map(item => Number(item));

function 답(a, b) {
    console.log(a - b);
}
답(input[0], input[1]);

6. A/B

const fs = require('fs');
const filePath = process.platform === 'linux' ? '/dev/stdin' : './input.txt';
let input = fs.readFileSync(filePath).toString().split('\n');

input = input[0];
input = input.split(' ').map(item => Number(item));

function 답(a, b) {
    console.log(Math.floor(a / b));
}
답(input[0], input[1]);
