### Minutes Between Events

Integer division separates higher decimal/time units, while `%` returns the remainder. These two operations let a program isolate digits or split a total number of seconds/minutes into components.

['Decide which part comes from division and which part comes from the remainder.', 'Mentally substitute at least one value for each branch and verify that exactly the intended branch runs.']

ANSWER Solution

const fs = require('fs');
const input = fs.readFileSync(0, 'utf8').trimEnd();
let [h1, m1, h2, m2] = input.trim().split(/\s+/).filter(Boolean).map(Number);
let a = (((h1) * (60)) + m1);
let b = (((h2) * (60)) + m2);
if (b < a) {
    b += 1440;
}
console.log(b - a);
