### Absolute Difference

JavaScript arithmetic works with numeric values stored in variables. A clear solution reads the needed values, computes the formula with `+`, `-`, `*`, `/` or `**`, and prints only the final result.

const fs = require('fs');
const input = fs.readFileSync(0, 'utf8').trimEnd();
let [a, b] = input.trim().split(/\s+/).filter(Boolean).map(Number);
let result = Math.abs(a - b);
console.log(result);
