A little bit of recursion practice using the game Tower of Hanoi

tower_of_hanoi.js

function move(ring, start, end) {
    console.log(`Move ring ${ring} from tower ${start} to tower ${end}`)
}

/*
 * hanoi()
 * @param - n = Number of rings in game
 * @param - start = starting tower
 * @param - end = ending tower
 * @param - aux = in-between tower
 */
var globalCount = 0
function hanoi(n, start, end, aux) {
    let count = 1;
    globalCount++;
    console.log(globalCount);
    if (n === 1) {
        move(n, start, end);
        return count;
    }
    
    count += hanoi(n-1, start, aux, end);
    move(n, start, end);
    count += hanoi(n-1, aux, end, start);

    return count;
}

console.log('Hanoi: ', hanoi(7, 'A', 'B', 'C'));
