"use strict";

process.stdin.resume();
process.stdin.setEncoding("utf-8");

let inputString = "";
let currentLine = 0;

process.stdin.on("data", (inputStdin) => {
    inputString += inputStdin;
});

process.stdin.on("end", (_) => {
    inputString = inputString.trim().split("\n").map((str) => str.trim());
    main();
});

function readLine() {
    return inputString[currentLine++];
}
/* Please do not modify anything above this line */

function main() {
    const myString = readLine();
    
    /* complete thefunction */

    let arr = myString.split('');
    let col = new Set(arr);
