### Lucky Ticket Number

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.

const fs = require('fs');
const input = fs.readFileSync(0, 'utf8').trimEnd();
let s = input;
let a = ((Number(s[0]) + Number(s[1])) + Number(s[2]));
let b = ((Number(s[3]) + Number(s[4])) + Number(s[5]));
if ((a) === (b)) {
    console.log("LUCKY");
} else {
    console.log("NO");
