// Lines that begin with two slashes, thus, are comments: they
// will be ignored by the machine.

// First we must declare a variable, n, suitable to store an integer:

int n;

// Each statement we address to the machine must end with a semicolon.

// To begin with, the value of n will be zero:

n = 0;

// Now we must repeatedly increase it by one, checking each time to see
// whether its square ends in 269,696.

// We shall do this by seeing whether the remainder, when n squared
// is divided by one million, is equal to 269,696.

do {
    n = n + 1;
} while (n * n % 1000000 != 269696);

// To read this formula, it is necessary to know the following
// elements of the notation:
//     * means 'multiplied by'
//     % means 'modulo', or remainder after division
//     != means 'is not equal to'

// Now that we have our result, we need to display it.

// println is short for 'print line'

println(n);
