### Triangle Existence

`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.', 'Mentally substitute at least one value for each branch and verify that exactly the intended branch runs.']

const fs = require('fs');
const input = fs.readFileSync(0, 'utf8').trimEnd();
let [a, b, c] = input.trim().split(/\s+/).filter(Boolean).map(Number);
if (((a + b) > c) && ((a + c) > b) && ((b + c) > a)) {
    console.log("YES");
} else {
    console.log("NO");
