### Smallest Digit

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 n = Number(input);
let a = Math.floor((n) / (100));
let b = (((Math.floor((n) / (10))) % (10)) + (10)) % (10);
let c = (((n) % (10)) + (10)) % (10);
let m = a;
if (b < m) {
    m = b;
}
if (c < m) {
    m = c;
}
console.log(m);
