++// Explanation of the control word:
++// - it's initialized to 1
++// - that means both the inner and outer loops start
++// - if there were no breaks, at the end of the inner loop, it's set to 0, which
++// causes it to exit (the inner loop is run exactly once)
++// - at the end of the outer loop, it's inverted, so it becomes 1 again, allowing
++// the outer loop to continue executing
++// - if there was a break inside the inner loop, it will exit with control still
++// set to 1; in that case, the outer loop will invert it to 0 and will exit too
