### Delivery Availability

`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.

NEED HELP? Hints

+

['Translate every case from the statement into a boolean condition before writing branches.', 'Check values exactly on the condition boundary: `=`, `<`, and `>` must match the statement without an off-by-one shift.']

const fs = require('fs');
const input = fs.readFileSync(0, 'utf8').trimEnd();
let [d, w] = input.trim().split(/\s+/).filter(Boolean).map(Number);
if ((d <= 30) && (w <= 20)) {
    console.log("AVAILABLE");
} else {
    console.log("UNAVAILABLE");
}
