### Smart Alarm

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 [d, v] = input.trim().split(/\s+/).filter(Boolean).map(Number);
if ((v) === (1)) {
    console.log("10:00");
} else {
    if (d >= 6) {
        console.log("9:00");
    } else {
        console.log("7:00");
    }
