const readline = require("readline");
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout,
});
rl.on("line", (line) => {
// 2种方式，第一种是lastindexof 另外一种 split
console.log(line.length - line.lastIndexOf(' ') - 1);
// const arrs = line.split(" ");
// console.log(arrs[arrs.length - 1].length)
});
