const readline = require('readline');
const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout
});

let input = [];

rl.on('line', function (line) {
    input = line.split(' ');
}).on('close', function () {
    let triangle = '';
    for(let i=1; i<=Number(input[0]); i++){
        for(let j=1; j<=i; j++){
            triangle += '*'
        }
        triangle += '\n'
    }
    console.log(triangle)
});
