### Days in Month

`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.

['Translate every case from the statement into a boolean condition before writing branches.', 'Verify the accumulator initial value and both loop boundaries; this is where off-by-one errors most often appear.']

const fs = require('fs');
const input = fs.readFileSync(0, 'utf8').trimEnd();
let m = Number(input);
if ((m) === (2)) {
    console.log(28);
} else {
    if (((m) === (4)) || ((m) === (6)) || ((m) === (9)) || ((m) === (11))) {
        console.log(30);
    } else {
        console.log(31);
    }
