### Leap Year

`if / else if / else` chooses a branch from boolean conditions. Comparisons such as `<`, `>=`, `===` and logical operators `&&`, `||`, `!` combine the exact rules that decide which output is valid.

ANSWER Solution

const fs = require('fs');

const year = Number(fs.readFileSync(0, 'utf8').trim());

const leap =
    year % 400 === 0 ||
    (year % 4 === 0 && year % 100 !== 0);

console.log(leap ? 'YES' : 'NO');
